Originally a naval expression. It means stop talking and be quiet. The Pipe Down was the last signal from the Bosun's pipe each day which meant "lights out" and "silence".
You better pipe down when she's talking to you!

a word created by my awesome twin which describes certain really awesome people (including myself). the exact meaning of this word remains undisclosed to all except for a certain few individuals who are not fortunate enough to be pindibbles and who have sworn secrecy about its definition.
