A set of crazy nightmares that remind you of someone crazy and/or violent. Mostly occurs when you are trying to get to sleep after a long day, or if you've been alone for longer periods of time.
Man! A gansy kept gettin' ahold of me last night, so I couldn't get back to sleep. All I could think about was her, from across the street.

Meaning Vagina, Fanny, Pussy, you get the drift.
Was down the pub the other night and this bird starts cracking on to me, I thought get in, anyways several drinks later we got a kebab and went back to hers, we were givin it the foreplay and when I went down to lick her PEUFF, she had a git sopping gansie what foyed, stunk worse than a fish factory it did.

Hey up John see her over there, Susan she's called, her gansie stinks but she fucks for England.

And as recited in a Jerry Maguire style "SHOW ME THE GANSIE!!"
