A brain that belongs to a tard. A tard brain rarely functions and on the occasion that it does function, it's gonna make a blunder. All members of tard fam have this type of brain and the tard brain was most likely first discovered in their family too. Norman "Nick" is the oldest one out of the bunch so you can bet that he was the first one with it but then it spread to York and Mike Carlson among others. For some unknown reason, it seems like York got the runt of the litter here because his brain is wayyy worse than the other two.
*York at Noah's house for dinner and Noah's mom made enchiladas*
Noah's mom: Hey York, how are the enchiladas, are they just like your mom makes them?
York: Yea, my parents are good but they've been busy with the motel and stuff like that
Noah's mom probably wondering: What the hell is this nigga on?
Noah wondering: I knew this dude was retarded but I didn't know his tard brain was this stupid.
