Dirty Twenty

In Dungeons and Dragons, a roll that adds to 20 only after adding your modifier. Used to differentiate from a nat 20, as that roll means automatic success, where as a Dirty Twenty may not.

DM: Roll for initiative.
Rogue: Dirty Twenty.
Bard: Nat 20!
DM: Okay, so bard goes first.

Dirty Tweety

To have a bird defecate on your face for sexual arousal, leaving the person with a moustache.

For advanced uses, some even use the birds feces as facial cream.

Alessia asked Jordan to hold her lovebird over her mouth so that it can poop on her lip. She got a Dirty Tweety.
