A guy tried to PUA me once. Did the ridiculous "think of a time when you were very excited and filled with lust" thing, the touchy thing, the whole bit. I fucked another guy right in front of him.
(The other guy's opening line was "hi" followed by actual conversation, and he was both a sweet guy and a nice lay. I actually didn't mean to be in front of the PUA dude, this was later in the night and not direct revenge, but we were out of bedrooms and ended up on a couch in front of everyone because we didn't really care who saw us.)
