To put your penis in the anus of an unsuspecting female partner. This trick works best while the female is on top. While she is riding you, grab the base of your shaft with one hand and thrust it in and out of her vagina quickly, then quickly, on the next inward thrust, aim it right for her browneye, and voila!
Dude I was railin' Julie last night, and I gave her the old slip trick.

a trick you pull when its snowing. at night you go and urinate on the side walk so it freezes and gets slippery, then the next morning you wait until someone is walking toward it and when they are about to step on the spot you kick the back of there leg out and sock them in the eye and yell "YOUR A PIRATE"

optionally afterward you may continue to hurl insults(YOUR A HOMOSEXUAL AND NO ONE EVER GENUINELY CARED ABOUT YOU) and poop into his face (its usually funnier to shove the poop his mouth)

it is often wise to take precautionary measures like wearing a mask(so they don't know who you are) and a gun(just in case they find out who you are)
me"hey that guy is walking with his kids past the spot where I peed, should i give him a slip trick."

friend"quick this might be your only chance!"
