No wonder no one ever comes to my parties

I want to make up my own game.

People would sit around in a circle and one person would walk around behind people's backs, tapping people's heads and saying "biohazard, biohazard, biohazard..." etc until they tap someone's head and shout "compressed gas!" Then that person has to get up from the floor and race the other person around the circle.

The person who loses has to parse verbs in Arabic.

Sounds like a game that I wouldn't be very good at.
