The act of pulling out of a girl during intercourse, shaking your sack, and yelling "Yahtzee!!" while you throw your load on your partner.
"Dude, I totally gave my girl 'the Yahtzee' last night. Now she won't return my phone calls."

When a girl or guys vagina or anus is loose to the point where you have to stick your hand in and jerk yourself off inside of them, like shaking a Yahtzee cup.
Silviu's ass was so loose, I had to get my whole wrist in there and give it the Yahtzee treatment.
