A semen oyster is a disgusting lolcow who just sits in his room and masturbates all day. He doesn't move like an oyster and there is semen all over his room, hence the name semen oyster. He can be milked for his lolcow pearls and is more often than not a tranny.

Get the Semen Demonmug. The act of holding ones foreskin shut while orgasming only to release all of the semen at once in a shotgun-like manner.
