Retarded Jeremiah 

Just like the term "silly billy" except its longer to say and it does not rhyme. You can use this in most situations even if the person in question is right.

Dude 1: Is that a car
Dude 2: Nah dude its a tree stop being such dam retarded jeremiah!!!!

or:
Dude1: Is that a tree?
Dude2: (even though it is a tree) Nah dude dont be such a dam retarded jeremiah!!!!
