When a boy is dancing with a girl at a party and the two are face to face he does several moves in order to get with the girl. These steps include:

1. Grabbing her hands

2. Raising her hands slowly up to the ceiling until fully extended
3. Bringing her hands down to 180 degrees (think of a "t" shape)
4. The boy then moves his hands to her waist, pulling her in close and forcing her to do the same with her hands
5. Leans in for the kiss... and victory
Girl 1: Oh my god. Did you just hook up with that ugly guy?

This is a rule established on Comedy Central's show, Workaholics, that states when you accidentally see another man's penis, the only way to restore order to the universe is to show him your dick as well.
Then you have both seen each other's penises and you can go on living your daily in peace once again.
Adam: Hey Blake, where you going with no pants on?
Blake: Oh, I accidentally saw Montez's penis yesterday, so I'm gunna go show him my dick to restore balance to the universe.
Adam: Ahh, the Boy Scout Rule of D's, have fun.
