Me and a friend of mine have been in an argument for a while now. He was playing Call of Duty and a friend of mine asked why there is a gun called the "Speakeasy". My friend seems to believe that the speakeasy was a type of Tommy Gun used (like in Bugsy Malone). However I told him he was wrong and that a speakeasy was a place where people would drink during prohibition. Has the word speakeasy ever been used to refer to a gun in real life?
You might want to ask this in /r/linguistics.
It's more of a language question and as it is formulated now it could violate the "no throughout history" rule of this sub.
