raw, sweaty crotch or balls.
Boy was that mile jog tough, I am gaulded.
I used the thigh-master last night, and I am gaulded!
Among car mechanics, gaulded is description of a part (usually a fastener such as a bolt) that cannot be loosened -- either due to rust or neglect or heat or age.
I tried to get that U-bolt off the exhaust pipe -- no use. It's gaulded on.
