Double Stack

The act of taking a shit in a toilet already filled with shit because either
A.) It has become clogged or
B.) You're having a Double Stacking contest

J: Man, I was at Ray's the other night and had to take a monster shit, but when I got to the bathroom, the only toilet was already full of putrid shit!
DOOKIE: NO! What'd you do man?
J: Well I tried to flush it, but it just spun around a bit. There was no way I was gonna make it home without squirting all over myself.
DOOKIE: Dude, tell me you didn't....
J: Yep, I just Double Stacked it.
DOOKIE: FOUL!

stack in the deck

Is when you shove your penis in a deck of cards and ask your sexual partner, "Pick a card any card." He/She will be tempted to pick your dick and then suck it.

He pulled a stack in the deck on me and it worked.
