The sexual act of spitting/ejaculating into your partner's mouth. Then, the partner with the spit/semen, spits it down the first spitter's butthole.
I just ate hot cheetos, so I had a lot of spit in my mouth, so I asked my bitch if it was cool if I spit it in her mouth cuz she was thirsty. I was astonished when she asked if she could do some Repainting the Basement, but I obliged anyway, and it was worth it.
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.
