Slow gas leak

A stupid, souless, materialistically obsessed shell of a woman who, although physically attractive, possesses a personality as interesting as watching paint dry.

Usually accompanied by and annoying fake high pitch voice which makes you want to stab your own ear drums out with a HB no.2 pencil.

Mark: "So bro how was your date last night?"

Johnny: "Meh, she was hot but man that bitch was a slow gas leak forsure."

Mark: "Bummer."
