I remember the negative version of “see see oh playmate” (also known as “say say oh playmate”, “oh little,playmate”, etc), but not a dirty one. the negative version goes like this

see see oh enemy
come out and fight with me
and bring your dragons three (or m-16)
climb up my poisoned tree
slide down my razor blade
into my dungeon door
and we’ll be enemies
forevermore more, shut that door!
