when you let your hand(s) sit in your ball sweat like a soggy sock and then punch your friend until their face looks like it got stepped on by a cow

I let my hand sit in my ball sweat all day and then hit my little brother so hard his face looked like a pizza with extra sauce.
I sat in my ball sweat for hours and then hit my coworker so hard his face looked like it got hit by a brick.
