Tor*pe"do, v. t.

Slang term, referring to a "come on" tactic somtimes employed by well-endowed women to attract the attention of a man.
Describes the feigned accidental brushing or bumping of the breasts against the man's body, often the arm.

Example:
  "Dude, I just got torpedoed!"
  "Shut up. You're imagining things."

It is quite likely that most instances of "torpedoings" are completly in the imagination of the guy claiming to have been torpedoed. Most of them probably stem from accidental contact, for which the woman, if she is even aware of it, is often secrectly embarassed.

Still, some guys will make a huge deal out of having touched a woman's breasts, even if it was a complete accident. This is probably to make up for not actually being allowed to touch them by any women on purpose. Those who are so blessed rarely go around saying "Dude, I just got torpedoed!".
