TBB

A TBB is a true best friend that you can always count on no matter what. it is someone that you look up to, and someone that will always have your back. You and your TBB should have an infinite amount of inside jokes, and code names for ugly people. Your TBB is basically the closest person in the world to you. even closer than your SIBLINGS! you care about your TBB more than anybody in the whole entire world, and you are willing to do anything for them. you always support your tbb no matter what, even if the like pot heads, or creepers. your TBB thinks everything you do is perfect, and nobody and nothing can stand in between you and your TBB. TBBs for life!!!

Taco Bell Butt. This is when you have Taco Bell and have very bad case of diarrhea.

I went to Taco Bell the other day, and had the worst TBB I have ever experienced.
