The act of inserting one's penis (usually of the abnormally large type) into another's vagina or anus in a very fast and brutal way. It is best done when running into someone while they bend over. Trains re known to be extremely good at this.
Girl: Shunt my asshole Daddy, all 15 inches of you
Guy: Ok
Girl: Ouch, call a fucking ambulance, you tore my fucking rectum

The revolting result of a girl's choice to whipe her ass from the front, dragging mad doo-doo across her cunt, which inevitably gets lodged in the folds, leaving doo-doo butter and the occasional peanut for unsuspecting guys to deal with.
After buying the chick like seven drinks, I get her home only to discover she was dragging a shunt around under that skirt all night--I did her anyway.
