Extra stupid, more than really stupid, absolutely moronic, having a really low
IQ, to be used when just plain stupid is not even close to describing how stupid someone or
something is.
Example 1
Guy 1: Last
night a fly landed on my brothers crotch. He took the hardest
swipe he could at it and totally nutted himself.
Guy 2: Unbelievable. Your
brother iis industrial strength stupid.
Example 2:
Guy 1: My showoff neighbour changed the oil in his driveway on the weekend. He forgot to put the drain plug back in. He poured 5 quarts of oil, straight through his engine
block all over his concrete. Then he hops in it, drives away and makes it to the end of the street before his engine seized.
Guy 2: Wow. That was a really industrial strength stupid thing to do. But since he's a douche, it's kind of funny.
