blow

Normally a slang term referring to powdered cocaine. However, for people in the metropolitan Washington DC who don't know any better, this term is used to refer to powdered heroin, apparently because the term coke refers to crack here because it is the predominant form of cocaine found there.

blow-by

1)Blow-by occurs when the explosion in your engine's combustion chamber causes fuel, air and moisture to be forced past the rings into the crankcase. Your engine's rings must maintain an excellent fit in order to contain the pressure.

2) Blow-by also occurs when somebody who REALLY needs to take a dump lets loose a fart so putrid and heinous, that it smells as if he just crapped his pants.
Daaaaamn Shecky! *cough* Judging from the stain on your trou, that wasn't mere blow-by.
