What is the origin of the phrase ‘hotter than a $2 pistol’?
Years ago, someone told me that it came from the FP-45 Liberator pistol, which indeed cost about $2. A cheap pistol like that would get hot; but since it was a single-shot, I don’t think it would get hot enough to evoke the phrase.
Hotter than a two-dollar pistol - Very hot, an allusion to cheap 19th-century pistols that go hot when fired. From the Mountain Range chapter,“Facts on File Dictionary of American Regionalisms: Local Expressions from Coast to Coast” by Robert Hendrickson (Facts on File, New York, 2000). Page 376.
I’d say it has a more negative connotation: someone hiding out from the cops is “hotter than a $2 pistol” for everyone hiding him or around him. I can think of more uses of it that way than as in “damn, she’s hot!”
I’ve also heard it used for heat-hot: “Damn, that lawnmower’s hotter than…” “That sun is…” “This room is…”
But metaphorical bad-heat trouble is what I’d put as definition #1.
Although I’ve heard the phrase, I think its actual use is rare. Interestingly, Ngram Viewer for "two dollar pistol"shows a sharp rise in printed use from about 1964 to 1977 and then a precipitous drop from 1978 to 1985.
Hotter than a $2 pistol is going to mean, hot as in do not want to hold it for any period of time. IF someone sold you a handgun for $2 they wanted it out of their hands for deniability purposes.
