My short definition for "meef" is this:

"It means funky. In a bad way. Like grandpa's laundry hamper."

This is a word that comes from the German word "mief", which means "an oppressive atmosphere, foul odour, pong, or stink". A German synonym for meef is "gestank". (Does that matter? Perhaps not, but I do think it's a hella funny word.)

I first heard "meef" used by my geek friends from Alberta around 1999. It successfully took root in East Vancouver after a great migration of programmers, DJs, and live P/A geeks to East Van in the late 1990s. In my experience it is normally used as an expletive ("Aaaah! Meef!"), a noun, or an adjective.

A male queef

When a man squeezes his buttcheeks when he farts so the fart hits his testicles.

Meef is a word that means whatever it needs to mean to fit the context of the situation. Though often used to replace swear words, it can take on a variety of meanings defined by the context.

1. A word to say when you have nothing else to say.

2. Used when watching a sporting event and the other team just barely wins.

3. Skank, Bitch or Whore. Used esp. with describing dates.
