When a man is soooo drunk that he passes out naked on his back and eventually starts to piss, straight up in the air, spraying EVERYTHING in sight.
Guy: Bro, you wont believe it, this total slut took me home last night.
Friend: Noice! Do tell.
Guy: Well, I blacked out and came to with her screaming that I had let the "Iowa City firehose" loose on her.
Friend: Ha! Dooshkabob.

A classic example of a "firehose" remark-reaction is when Jimmy Culp does an astonished "sploooot!" when he hears his name mentioned by Robert Stack on the Tonight Show immediately after taking a deep swig of beer.
