Poppin the Dirty Elmo
After having rough sex, the dude pops his red balls (resembling elmo) into the chick's ass, thus making it dirty. Afterwards, the chick can either lick it off, like a lollipop, or just enjoy the ball to anus pleasure. The definition is quite flexible.
Example 1 (balls into anus):
Dude1: Dude, she's so hot.
Dude2: I'm gonna enjoy poppin the dirty elmo.
Example 2 (lollipop licking the dirty elmo):
Dude1: Dude, I hear she's quite rough in bed.
Dude2: I hope she enjoys poppin the dirty elmo.
Dude1: Dude, she's so hot.
Dude2: I'm gonna enjoy poppin the dirty elmo.
Example 2 (lollipop licking the dirty elmo):
Dude1: Dude, I hear she's quite rough in bed.
Dude2: I hope she enjoys poppin the dirty elmo.
