Brainal 

When a female (or male, depending on your preference) performs fellatio on you after anal sex before cleaning the penis.

You, this chick Natalia is mad nasty, she gave me some brainal last night after I was up in that anus for like an hour.

brain drain guilt 

The guilt that comes with leaving your city for a more affluent area after college, despite the best attempts of your professors and others to prevent it.

Paul: "I had this crazy dream last night. I was on trial for planning to move to Chicago, but the jury was made up of my professors. When the judge asked for the verdict, one of them stood up and said, "We have no verdict. We're just extremely dissappointed in him."

Bob: "Sounds like you have a serious case of brain drain guilt bro."

braineurism 

1. An idea

2. A thought

Hey, I just had a braineurism. Remember when we were talking about that thing earlier, you could do this and it'd be a lot easier.
