So I went to a foam party for the first time. I've got to say, it has potential to be fun if you're drunk, but I was underage and couldn't drink while I was there.
A radio station hosted it, so they were throwing free stuff into the big room of foam while everybody scrambled to grab them. There were some concert tickets, which I unfortunately I didn't get. However, I got 6 or 7 condoms, a vibrating cock ring, coupons to a local sex shop, and a whole bunch of packets of lube so I guess it's okay.
Only problem was though the foam (which I'm assuming was soap duds or some shit) literally choked you if you went under. I had to keep myself from vomiting and I had to jump out of this room and sit in the corner and dry heave until I was okay.
TL;DR: Don't go to foam parties. The foam burns your eyes, suffocates you, and ugly people dry hump each other in the corners of the foam room.
