Also known as OSSD.

When an individual finds it incredibly difficult to converse or interact with a person of the opposite sex.

Also occurs when an individual can interact with a person of the opposite sex, but speaks without thinking, offends them without knowing it, or just doesn't know how to treat them. This can be seen in terrible boyfriends/girlfriends, pimps, annoying nerds, and short white freckled kids who think they're tough.

A nicer way of saying the phrase, "PISS OFF, PISS ANT"; basically telling somebody to go fuck themselves.
Piddle is another word for piss, and wingless hymenoptera is another way to say ant -- in particular, a female ant because males of many species do indeed have wings.

Works better when written or typed rather than when spoken.

The all-caps presentation is intentional; you want the recipient to think that you're shouting.
