literally translated from french to mean "good who who," it can be used for talking on the sly about someone who has a good hoo-hoo, since
people will think you're talking about the madtv character and not someone else.
it can also be used to describe a girl who's a good lay but is overly
ghetto and/or
white trash.
"i banged that chick last
night...she was a bon qui qui."
"that girl is
disgusting...what a wanna-be."
"
yeah, but she's a bon qui qui. we did it eight times last night."
