A doohah is given to the first person to fall asleep at a party. A third party volunteers to run for a few kilometres....generating
sweat and body odour. The sweaty person then wipes the
sweat and stench from their arse crack on the sleeping person'
s upper lip. When the person wakes up, they spend the rest of the night trying to figure out who farted and/or shit their pants.....without realising where the smell is coming from. Works better if no-
one tells them what has happened.
