Greg, like I said... really, I think it was a combo in that case of the subject in discussion at that time and the allergic reaction--not trying to present as a tough guy, and I was trying to play that retelling of the story for laughs.
If I were putting money on it, I'd say it was an allergic reaction to the fish primarily (I'm allergic to all seafood and somebody forgot to tell me that a dish at the potluck had fish-sauce in it), and this poor schlub just happened to both give the Straw That Broke The Camel's Back AND be standing in the wrong place at the wrong time, a "Perfect Storm" scenario. Either of those two hadn't been in play, and I think I probably woulda safely made it to the men's room for my un-load.
Hope that helps clarify things and keep the peace. :)
