newbie -- what do abbreviations mean?

So I am new to Austin, and new to the scene. Have my first meeting tomorrow, very excited!
Been doing a lot of reading of reviews of the ladies on here, and can't decipher all the abbreviations, some are obvious, HJ, BBJ, but many I can't at all figure out.
Anyway have a crib sheet to what they all mean?

thanks!

TOFTT is the most important one to learn and you don't want the t-shirt.
