look up any word, like sex:
1. Possesing an abnormally amount of strength given a small size.
2. Being as strong as a mentally retarded person, even though they are not mentally retarded.
3. Mentally retarded people are abnormally strong, so don't mess with them
1. I can't believe little Billy was able to lift up that piano all by himself, he must have retarded strength.

2. I was'nt able to stop Billy from kicking my ass because of his retareded strength.

3. Billy's mother does'nt keep a jack in the car, because Billy has Down's Syndrome. He has enough retarded strength to lift it up so she can change the tire.
