When a man has sex with a woman Doggy-style and imitates a firetruck sound and later when he cums on/in her he'd refer to it as putting out fire.
Samantha: "Jerry kept hooting while we were doing it doggy style yesterday."
Lois: "Ah. You mean he did the Fire truck..."
Samantha: "No wonder he was yelling 'put out that fire big guy' when he was cumming!"

1) A vehicle which carries firemen and fire fighting equipment to the scenes of fires.
2) A substitute for the word "Fuck", which has risen from a (false) rumor that Soupy Sales said on his kids show "What starts with F and ends with UCK?" Firetruck!

2) Go firetruck yourself.

A word originally describing a vehicle that puts out fires. However, in recent times it has come to be used as a replacement for the word "fuck", as removing the "-ire tr-" from "fire truck" will give you fuck.
