To compensate a male for a kind act with oral sex.
When her car broke down on the way home, a guy stopped and gave her a jump. Brandy thanked him with a blowjob.
I didn't have any money to tip the driver and he was cute enough so I gave him a Brandy thank you.
(Porn + horny = Porny.)
Being porny is writing or acting normally but then going into a naughty or sexy mood to arouse the other party.
You can do this in casual conversation, texting (turned sexting) or email.
Me: I was texting him and all of the sudden he was being porny and really descriptive. It was weird for
a study buddy, right?
Friend: Ewwwww! Yeah, totally weird!
