a party foul is when you screw up at a party.

note: The band Yellowcard gets its name from party fouling. You get a 'yellowcard' like in soccer if you party foul.

An amazing song by the band Attack Attack!

Doing something stupid in a big group of people, e.g., a very crowded party, which results in a non-life-threatening but nonetheless unpleasant incident.

When a indivudual or group of individuals does something that completely goes against the feel of the party and ruins it for everyone else.

When multiple people are smoking a hookah, and someone kills the suction from your hose by uncovering their hose. Causes the smoker to have a coughing fit. When a party foul occurs, the foul-ee gets a slap on the hand as a punishment.

A big bucket of KFC. Yummy!

Not being cool at a cool party and sending everyone home...
