pop fly

This refers to the baseball euphemism for sex. 1st= kissing, 2nd= touching boobs, 3rd= touching genitals, and a home run would be sex.
A pop fly=oral sex. A pop fly can be hit at any time and does not always fall in line with "bases," as is the case with oral sex; it can come at any time, usually after 2nd or 3rd. It can also occur after a home run is scored.

"So, did you get any this weekend?"

"I rounded 3rd. On our next date I'm gonna try to hit a pop fly."
