RBI

Really Bad Image.

This is what happens after TMI. Additionally, when you see something really horrible.

Tim: I just saw a dude eat a booger.
Tony: RBI, man.

RBI

Rectal Ball Insertion. When a guy manages to get his testicle into a girl's rectum. To this day, there are no reported cases of the RBI.

We were getting bored with our normal routine, so last month I decided to go for RBIs.

It really, really hurt my balls but I got them in there. I'm up to 5 RBIs this season.

RBI

When your friend is having trouble getting up to and beyond third base with a somebody, but you do or say something so that they end up having intercourse.

Charlie was having trouble getting to home plate with his girlfriend, but I earned an RBI by getting them both drunk and alone at that party where they finally had sex.

Lisa wanted to have sex with Gary but he was clueless, so I set them up and they went all the way, earning me an RBI.

I earned an RBI when that guy came over and asked me if I had a spare condom so he could make love to his lady for the first time.
