Boner Sweats 

Tight sweatpants that when worn accentuate the engorged male genital.

Dude, did you see Joe? He has his boner sweats on... awkward.

Sweatshirt Boner 

The bump that sticks out when you sit while wearing a zip-up sweatshirt.

...Everybody's got them, but nobody wants them...

I shouldn't have worn my new zip-up hoodie today. I had to hide my sweatshirt boner every time I sat down.

When it's so hot and humid outside and your ass and taint area sweat, you get an erection just by your wet underwear.
