Sack tapping

Sack tapping is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sack tapping rather than just read about it. In short: Sack tapping is a slang term for a game where a participant attacks, by slapping, tapping, punching, kicking, elbowing, twisting or backhanding, another male’s testicles. The term derived from 'sack', slang that refers to the scrotum, and the activity is a form of groin attack.

Key takeaways

Sack tapping belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sack tapping to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sack tapping from memory before moving on to harder problems.

Reference excerpt

Sack tapping is a slang term for a game where a participant attacks, by slapping, tapping, punching, kicking, elbowing, twisting or backhanding, another male’s testicles. The term derived from 'sack', slang that refers to the scrotum, and the activity is a form of groin attack. This sociological manifestation of bullying can result in severe testicular injury that may require amputation as the only form of treatment. A reported increased popularity of sack tapping, fueled in part by YouTube videos, and the subsequent increase in hospitalization has concerned parents and urologists. It is also called "nut tag", "bag tag", "sack whack", "bell flicking" and "roshambo", the last name coming from an episode of South Park that featured the practice.

Sociological impact In 2010, a participant lost a testicle caused by physical trauma that resulted from a sack tapping assault at school. ABC News' chief medical correspondent Dr. Tim Johnson commented, "the trend isn't restricted to Minnesota", and has "gotten out of control" as per Dr. Scott Wheeler. Dr. Wheeler, a urologist in Minnesota, has seen an increase of hospitalization caused by "sack tapping" incidents, and commented that criminal charges could be filed against the attacker as a result of the one instance. The casualty survived the surgery and can function normally with one testicle. The casualty's mother saw "what he went through every day" and withdrew his enrollment from school. "Sack tapping" has grown into a more dangerous game that can result in greater injuries. Dr. Wheeler recommend that parents warn their children of the dangers of "sack tapping". Jack Shafer, writing in Slate magazine in 2010, commented that despite the media describing sack tapping as "the latest dangerous craze", the practice was not new and had existed for some time, and the recent focus was simply "sensationalist journalism". He claimed to have been "taking shots to my crown jewels when I was a 1960s teenager", adding that the term had been listed in the Urban Dictionary since February 2003. He noted that urologists were not polled regarding an increase in such injuries, and were only asked to confirm that such injured were common.

Worked examples

Example 1 — a first encounter with Sack tapping

Start with the simplest possible case. Write down what Sack tapping claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sack tapping before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sack tapping ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sack tapping

In research: Sack tapping appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sack tapping in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sack tapping is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2000s fads and trends, Harassment and bullying, Problem behavior, so understanding it makes those chapters shorter.
In everyday life: Look for Sack tapping outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
