The ultimate bond of brotherhood. To guys pee at the same time and try cross streams with each other. The ability for them to pee in front of each other resembles ultimate trusts in each other. The bond formed is stronger then the bond between Siamese twins.

A guy peeing in a toilet while his girlfriend (girl) sit on the toilet and pees at the same time.... The action is the girl sit on the toilet while the guy sits on her lap opens her legs and pees at the same time. The position on the man and women is that one the urine flows the 2 two streams of urine intersect each other.

Crossing the streams: When you're urinating and defecating at the same time, and you maneuver your body just right so you can urinate on your feces while it's coming out.
This isn't a sexual act, but I'm sure someone can figure out a way.
"Dude, I just pissed on my shit while it was still coming out. It was awesome!"
"Yeah man, I cross the streams all the time."
