best yo mama joke gets a little name addon that they can wear in servers, where ever someone beats theirs the new person takes it and adds it to their ingame name and old person removes. The title is "[KOYM]" (king of yo mama)

just though it will be a laugh xD if u wanna make a competition of it feel free,
because i made the idea ill start
to mama's so fat she sat on a rainbow and skittles popped out! ohhhhhhhhhhhhhhh!
Note: next joke hast to be funnier by vote sorta thing then the previous otherwise title stays with original winner. less funny ones means try harder next time
