GeronimOUCH! 

When you purposely give your own erect penis an indian burn.

I gave myself a GeronimOUCH! so bad, that my cockskin started to split and bleed.

GeronimOUCH! 

What sky-divers yell when they jump out of an airplane at an altitude which is too low to allow their parachutes to open, but too high to keep the sky-divers from becoming the pizza sauce on an upside down parachute pizza.

As Scooter jumped out of the airplane 187 feet above the ground, he yelled, "GeronimOUCH!"

Geronimous 

Anonymously jumping yelling geronimo...

Geronimous is a stupid word.
