The female equivalent of pump and dump, i.e. when a girl uses a guy for sex (such as a one night stand) and then ghosts, i.e. doesn't respond to him trying to get with her again.
"Man, I thought I could make Amy my f***- buddy but I guess she pulled a ride-n-hide on me. She won't respond to my texts any more."
Like hide and go seek. A group of (normally teenagers) divide into boys and girls. one of the groups will go and hide while the other group searches for them. When a girl/boy finds one of the other group, they then have to grab them and say "1-2-3 HIDE-N-RIDE" they then proceed to "Ride" (have sex).
The young man searched for the girl. Found her, caught her, shouted "1-2-3 hide-n-ride"....they then proceeded to have sex.
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
