The piss most men take directly after masturbating (and orgasming) that hardly ever gets in the bowl, no matter how hard you try. It may splash against the walls, get on your clothing, all over the floor around the toilet, and the toilet seat, but rarely the actual toilet bowl.
Guy1: Dude, I just masturbated
Guy2: Did you take your post-masturbatorial urination yet?
Guy1: Yeah, it was horrible, my boxers are soaked and I spent 5 minutes wiping piss off my wall with toilet paper.
