Related to Texas Holdem Poker. When a player, plays 2 consecutive hands BLIND ( not looking ).

The 1st hand winning and reveling very poor cards, ( example a 7,2 offsuit )..aka the DONK.

The 2nd hand also winning but reveling good cards, ( example A,A pocket aces ).. aka the SLAM

The conditions of the situation may vary, but the main things are that both hands must be played BLIND entirely until they are reveled at end of hand. The 1st hand must be considered a junk/ non playable hand. And that the 2nd hand must be a very good hand pockets/nuts.

Get the Slam Donk mug.
A girl with a big booty who is virtually guaranteed to let any and all dudes hit it. She may not have sex with all of those men, but she is very flirty. Often found drunk on the middle of the dance floor at crowded clubs grinding on virtually anything at all.
"Yo, you think I got a chance with Keshia?" "Sure thing man, she loves throwing that booty around. She's a slam donk."
