look up any word, like blumpkin:
Grude; Not being able to tell if someone is a Girl or a Dude so it is a Grude.
Hey Camron I can't tell if that is a Girl or a Dude.

Damn Mike it must be a Grude!

Grude is when someone (a girl) puts icecream on her finger and then fingers herself afterwards she tells a guy to like it off. Which means he will be eating ice cream and eating ice cream at the same time.
Do you wanna lick my gurde?
