Spider's Web 

You and the lads each buy individual electric fly swatters, sit in chairs, then place the electric fly swatters over your genitals. One of you then puts pornography on a phone or larger screen for all to view. The goal is to not get an erection, to therefore not get an electrocuted penis.

"Hey man wanna do a spider's web?"

"Fuck no, dude it felt like I burnt my dick off last time."

Having just relieved yourself in your hand; the act of then throwing your spunk across the room in the exact motion that Spiderman would release a web from his wrist.
