6blow
6blow, also known as 6.0 is a slang word for a 6.0 ford powerstroke Diesel engine. It got the name 6blow for blowing headgaskets. Although they have a very nice sound to them, they are almost as unreliable as your girlfriends pussy on her period.
“Yeah man my 6blow was screaming almost as loud as your girlfriend last night, too bad I blew a head gasket and your girlfriend’s pregnant”
