It's Shane and Don's lingo, Amos, not mine. It can mean 2 things:

1. When uttered contemptuously or in a hostile way "skank" means:

- an unattractive, sluttish, slatternly girl/woman who is low class, foul-mouthed, and undesirable. ("I would not flippin' waste my time on her, eh?")

however....what it REALLY means in that case is...

"She flippin' turned me down, man!"

2. When uttered in a good-humoured way on the other hand, it means:

- "A local babe who I figger is pretty easy, eh? So maybe she turn me down..."

3. The equivalent British term is "slag".
