Upskirt mania is the phenomenon when a girl bends over in a miniskirt, and you get a flash of her sexy cheeks. Upskirt mania is improved 100% when the hot female is wearing a thong – improved 250% when she is commando.

Side effects of upskirt mania: extreme hard-on and an insatiable itch to fuck
Male 1: Holy shit, did you see Leah bend over just now?
Male 2: Yeah! I think she's commando, dude!
Male 1: Fuck. I just jizzed in my pants.
Male 2: Me too, man. Me too. That was the best upskirt mania ever.
