onion bomb

The worst smelling far known to man. Made from eating the little chopped up onions from a McDonalds cheesburger or any other patty burger in which they are on. The smell derives from the circular motion is made while syphoning out the smell of the 'onion bomb'

After eating at McDonalds, I left a few onion bombs in my buddies car they stayed in the cloth of the seats for weeks...
