D.B.T.K. 

An acronym standing for "Done Before The Kettle".

A slang term used in Manchester, England to describe the act of fellating someone in such a manner that they ejaculate before the kettle has finished boiling.

Mainly used to describe males that ejaculate in less than 30 seconds.

"Man, Dave was done before the kettle just now."

"I just did a D.B.T.K. again..."

Manhattan B & T

People, usually of the lame sort, that come to "hip" neighborhoods in Brooklyn to party on weekends. Oftentimes consisting of the same brand of chodery that takes over the L.E.S. on a Saturday night.

Sea isn't really that great, and furthermore, it's always filled with Manhattan B & T
