The act of inserting a non-erect penis into a vagina then having it becomes erect inside said vagina to give a push pop feeling
Person 1: "I didn't get it up in time so I just put it in flaccid."
Person 2: "How did it feel?"
Person 1: "Like a push pop just the other way around."
Person 2: "So an inverted pushpop?"
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
