(Masculine)

1: When you are spotting someone while they're bench pressing, and when they can't lift the bar, you try to help them lift it, but your center of gravity isn't very strong. Because of this, you center your pelvic floor above the other incapable person's head/face. The result is a face full of sack for the sweaty victim.

2: When someone is struggling to bench press and needs a spot, butinstead of a spot, you feed them your nut sack
-I was trying to hit a p.r. on bench the other day when I got bench sacked by my spotter!
