Thick-Skinned

 is a quirk Wasteland 2: Director's Cut.

Description
All the boys 'n girls in the playground used to pick on you. They called you stinky, fatty, ugly, and beat you up until you were bruised and sore. But the more you took it, the more you learned to shrug it off. Sticks and stones won't break your bones. Years of physical abuse have left you thick-skinned and you can shrug off attacks more easily, but you're heavier and more sluggish, and as a result, you move slower.
