belt buster 

a hard-on or boner that you get when you are aroused

That kid Sunghi has a belt buster when he sees kathy.

Belt Burster

A dump so titanic, savage and undeniable you are forced to unfasten your belt in order to relieve the pressure until you can get to the sacred throne to void yourself.

Never eat five pounds of sauerkraut after three pounds of spicy reindeer ghoulash, that always gives me a serious belt burster
