What is Cumass?
1.
Instead of calling someone a fag or gay, "cumass" substitutes any word refering to a homosexual. It literally means a man or in some cases a woman or hermapherdite who has undergone HBS and has remnants of semen in the anal cavity.
After Faye and Erroll had bad hott butt sex, Faye was considered to be a cumass due to Errolls ejaculations in her anus.
