Boner Piss 

When having to take a drug test and the urine going into the cup comes from a boner; usually in the morning

I didn't want boner piss in my urine sample, so I had to wait until my hard-on went away.

Piss Boner 

A morning erection usually alleviated by urination. Usually dry-humping or twisting around your dick would feel good in this instance. And, when you urinate, you need to do a handstand or pull it down. Even if you do these things, your urine will definitely go everywhere, since morning pisses usually include piss flying everywhere randomly, even disobeying the laws of gravity because of what I can only guess is dick boogers (eye boogers, but in your dick hole).

I had a wicked piss boner this morning.

Piss Boner 

When your dick gets hard because it's inflated with piss.

Mike : "Oh my God, Jeremy has boner! Is he really turned on by that ugly bitch?!"
John : "Nah, it can't be - he probably just has a piss boner."

A guy wakes up with a piss boner when he doesn't totally unload before he goes to bed. This can be especially embarrassing when living with another man or when explaining the concept to a female when under the hysteria of the midnight mindfuck.

I laid in bed for at least an hour this morning and the piss boner I had never went down. I basically had to masturbate to get it to a size reasonable enough to get out of bed with.
