look up any word, like turnt:
When you want to buy a cheap prostitute, and you don't have any money, you do a gellO.

Oh, you just gellO'd that hoe! you took a hit-n-run.

"Mommy, my gello got hurt. I was riding my off brand banana seat bike, when I ran into a bush and slid off the banana seat into the handle bars and that is when I hurt my gello."
