Does "cross swords" have the meaning "two or more guys are having sexual intercourse with a woman and accidentally touch penises" as an idiom?

Sorry for the vulgar language.

To cross swords is a well-known idiom meaning to argue vehemently. It probably originates in the Medieval period of history when gentlemen settled disputes by dualing with actual swords.

Urban dictionary does have some homosexual references to this phrase though.

Well, according to urban disctionary it can mean that, and it can also mean that two men are peeing into the same toilet (or bush, or whatever) at the same time. I've certainly never heard it used these ways, but then I really don't have very many conversations regarding simultaneous use of two penises.
