The tap 

When a woman is so unsatisfied with a man's sexual performance, she taps him on the shoulder, indicating that she's tired and just wants to go to bed.

Popularized by Seinfeld.

I can't believe it! I really thought I was zone, but then she gave me the tap.

The Tap Rule 

The one prevailing law during a gangbang that creates order from disorder. After a reasonable period of time has passed, the gentleman who's "on deck" may tap the shoulder of the gentleman currently "at bat," and the latter gentleman must step aside and let the next guy have his turn.

This rule also works for drinking at a water fountain.

The Tap Rule was popularized during one particular scene (I believe it was No Holes Barred 4) where a certain anonymous man repeatedly ignored the aforementioned shoulder tap and was sternly reminded by one the men standing by to, "Respect the Tap Rule."

Rather than let the normally enjoyable experience turn to violent anarchy, the man relented and allowed the next gentleman to put his hoohoodilly in the female participant's cha-cha or whoopsidaisy, thereby preventing possible bloodshed.

The Tap Game

A very simple, yet amazingly fun game in which you, and bunch of your buddies open up a high school yearbook, and in a circular-fashion, each selects a girl in the book, and asks himself the question, "Would you tap that?" The person then reveals to the group if he would have sexual intercourse with that girl. Play passes to the left. Disagreements over particular "chicks" often lead to discussion and debate, which further adds to the entertainment.

Johnny- Let's see, Betty Sue...she has amazing tits so yeah, I would tap that.

Billy- Yeah, but Betty Sue is as ugly as shit. Mary Ann, on the other hand, is fucking gorgeous. I would most certainly tap that.

Vladimir- Isn't the tap game amazing?
