A girl or woman who is the ugly, disgusting girl in the group and also the most annoying. She also is the girl that cock-blocks guys trying to get on girls in her group because she is not getting any attention.
Chutz was supposed to get it on with The Scrog of the group, but she was so disgusting he went inside and jerked-off. The girls that Gregor and Tody were going to get on then wanted to leave.

The Scrog was so disgusting she reminded me of a 5'2" Randy Moss.
