1.) a girl who gets so severely intoxicated at a party that despite how good looking she may be, her rambling and overt slutish behavior turn her off to everyone (sometimes can be used toward a male, but that can be risky)
2.) a party that is either one of epic proportion or spans more than two consecutive days (the latter party mainly occurs with large groups of hippies)
"Remember that time I sold my Volkswagen and bought enough LSD to keep us tripping for a week? That was a total slopfest, man."
2. mcdonalds, burger king, taco bell, wendys, pizza hut, jack in the box, hardees, 7 eleven, kfc, country buffet, or any similar fast food establishment.

when you go to a party and all of the people are incredibly wasted. all of the girls are getting sleezy, the noise levels are way too high, its really hot from all of the sweating people, and the cops could be showing up any time.

2. A person who is acting sloppy usually due to intoxication
