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.
