oversquirt 

To be taking a crap, get a big boner, then start peeing uncontrollably over the toilet lid.

Dad: Son, why do you always pee on the floor??
Son: Sorry Dad, this time it was an oversquirt.
Dad: Gotcha.

over squirt

Like an over dose except the drugs are mixed with extreme masturbation from watching PornHum while partying. This is a common problem with a cartoon character named Ira on Unauthorized.TV

To quote Ira from a cartoon titled: Life of Ira - "Last I night I mixed meth and viagra then ended up at the Glory Hole for like eighteen hours and almost died from an over squirt. Oh Jheezus my bowels are all messed up , and I think I just shit my pants . Oh Jheezus I'm squirting again!"
