A piss-boner is the hard-on a guy gets, usually in the morning, maybe related to morning wood, that a guy gets when his full bladder is pressing on his prostate gland.

A morning erection usually alleviated by urination. Usually dry-humping or rubbing around your junk 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 urinations usually include urine flying everywhere randomly, even disobeying the laws of gravity because of what I can only guess is penis boogers (eye boogers, but in your man hole).
I had a wicked piss boner this morning.

MBMP, MBMPing or Morning Boner Mangina Pissing is the only alternative to attempting to piss with morning boner and subsequently pissing all over the walls and floor of your bathroom. It is a simple technique, unconventional, but highly effective, wherein you stand with your ass facing the toilet, take your four fingers with your thumb extended upwards at a 90 degree angle, and fold your dick back between your legs as if to create a mangina.
Then, bending over and looking between your legs at the toilet behind you to ensure you do not miss the bowl, you proceed to piss, firmly holding your morning boner in place to prevent it from springing up and wreaking havoc.
Using this technique will allow you to avoid pissing in the shower or having to painfull force your boner downwards
Example #1:
Steve (to Bill): I can't stay over at my girlfriend's house anymore man
Bill: why not?
Steve: her mom caught me morning boner mangina pissing last time and now thinks I'm some sort of queer.
Bill: she obviously doens't know anything about dealing with a rock solid, red hot morning boner.
Steve and Bill: (yelling together) Morning Boner Mangina Pissing!
