A dirty shane is a beer bong hose with a face mask on the end of it. It's used to blow a Shotgun (definition 4) such that the recipient must inhale through both nostrils and mouth which results in a stronger hit.
This delivers a stronger shotgun with less wasted smoke, and eliminates the issue of shotgunning another person's boyfriend or girlfriend, as the dirty shane act's as an intermediary.
