Bombadeer
A safe word for males to utter aloud to eachother when they get an unexpected erection in a public place. It serves as an alert/warning to the fellow man that has also experienced the unexpected public erection, the Bombadeer.
(In a classroom)

Guy: *cough* Bombadeer.

Instantly, other fellow men understand, with the use of only one word. Females in the room remain clueless.
