When a man farts into a girl's butt causing the "wind" to travel through her insides and out her mouth in the form of a disgustingly stinky burp. Her mouth then smells like a fat, hairy guy's ass for 2-6 hours depending upon her penchant for hygiene.

This is often done in Windsor (Canadian city right outside of Detroit, MI) as everything in Canada is ass backwards and dirty...
I don't know whether this girl I met ate a pig's ass for breakfast or she ran to the bathroom and got a WINDSOR WIND TUNNEL from some dude...Her breath is nasty!
