While browsing the Internet, I discovered a scuba diving club in Ireland that goes by the name “**** Diving Club.” The gentleman next to me, who is not a native English speaker, proceeded to ask me, “what means ‘**** diving?'”
Mind you, the setting for this conversation was a professional office environment, so I limited my response to saying the meaning is sexual in nature.
From the look of the page, discovered through Stumbleupon, it is a real scuba diving club. The presumably all-male club apparently had fun coming up with an attention-getting name.
I am aware that this term could mean something entirely different in Ireland, but, in America, the only meaning I am aware of would be rated R.
