>>One doesn't call someone who's just had one over him a "loser" or a "putz" surely. If anything it's the subject of the joke who's the putz. I don't know what a nimrod is in this context. The word you used was appropriate in a way. I'd be more inclined to say "You swine!"

>Hmmm, swine. I do think loser would work fine here, kind of generic really, but your right regarding putz; probably slightly more harsh than would fit the situation.

No, no. As you'd just been duped, that makes YOU the loser, surely. I'm a gainer. I'm an SOB.
