How to understand comedy talk

There are a lot of phrases I have learned since starting standup oh so many years ago.  Here’s some inside baseball for the lay persons out there.

“I have a rock solid 25 minutes.”  Translation: “I have a decent five minutes, five acceptable minutes, then some rambling incoherence I sprinkle around those ten minutes.”

“You should do this room, the crowd buys a lot of merchandise!”  Translation: “There’s no hotel and the pay is shit, but I’ll try to entice you with the false promise of merch sales.”

“I slayed that room.”  Translation: “Were you at the show?  No?  Then I’ll tell you I slayed the room.”

“I’ve done corporate gigs.”  Translation: “I once did a joke in my office break room.  It was someone else’s joke.”

“That wasn’t my crowd.”  Translation: “Those people were normal humans, not complete degenerates like I need for my horrific set.”
