a gay man, a dangerous, dirty homosexual. one homo grabs anthoer homo's scotum skin with the tips of his fingers strectches out the skin. andd proceeds to nibble on it gleefully while making an "eheeheheeehe" sound like some diseased chimp.
Faggotus, the gay, was primarily a penis licker, wheras his jew lover, Shlomo Penus, was more of a scrotum nibbler.
