To vent your frustration; either loudly or through the Internet. Most people prefer the Internet, like going to VentNation.com or related sites, or going bat s--t crazy and ranting in someone's face. Sports fans and TV personalities enjoy ranting the most, and so do girls amongst their friends.
Person 1: Why are you ranting?
Person 2: Because I'm unemployed. I don't have a girl. I hate my life! FML!
Person 1: I HATE THE PATRIOTS. TOM BRADY IS A NO GOOD PRETTY BOY AND BELICHICK IS A BELICHEAT.
Person 2: Stop ranting and calm down!
Ranting is speaking your mind. Soft, spiritual minded people or groups call speaking your mind ranting when they don't want to hear about the subject. Soft, spiritual folks don't rant, they speak their minds. Only other people rant.
A bit like Dry-Humping, runting refers to two or more people simulating sex, while fully clothed. Runting differs in that it is 'performed' while dancing, usually drunk in a club. It's very obvious and hard to watch. It can be performed by either sex. Attention whores are the main advocates.
'Look at the state of Lorna, runting like a piglet.'
'I'll stay until you start runting complete strangers.'
'I'd a runting good night last night, or was it a good night of runting lol.'
Its the need to try and be the best at things and bust out facts that are clearly not true at all. And when that attempt has failed they go into this ranting fit that only ends with them getting thrown out of theremother's basement.
Chin: Dude my penis is not 3 inches. (recites some facts he heard from someone that are completely false.)
John: yes it is. Dont lie just live up to the fact and we can move past this.
Chin: Asian Ranting begins (Trashes around violently breaking thingsand yelling) No mom dont turn of the computer. (insert yelling in another language that is Asian between them) Dude, I gotta go.
