What is a foam party?

And why would somebody attend one of these?

I've attended dumber in my younger years.

A "foam party" is a get-together in which the participants are covered with foam while on, f'rinstance. a dance floor.

Presumedly someone would attend to either i. cop a feel or ii. have a feel copped from oneself.

Why would one NOT do that?

They had a foam pit at the local high school dance a few years ago. It was a disaster. The pit concealed all sorts of inappropriateness and the chaperones were freaking out. They vowed to never let another one happen. Everyone in the foam had really red irritated eyes for a few days too.

Well since you put it that way...maybe not so dumb.

They had an episode on CSI LV where someone was dead on the floor during a foam party.

I got invited to a styrofoam party.

It kept my coffee warm but it was hard to cop any feels
