To overkill a joke. When a joke is told by
one person and then someone else keeps
piggybacking and adding on to that joke until, at last, it has no humor
left in it.
Man, we were having a couple of beers the other night and this chick walked in with those UGG
boots. We all started laughing at her, but
Jimmy kep going and going and going. I felt kinda
bad, but he should've known he gained it.
