What does "tta" mean?

my friend posted this on one of my pictures saying "you wish u could get all that tta." i dont know if this is a typo but i got a feeling its some kind of hip ghetto talk. i dont want to ask her because shel think im not kool, especially after she accepted me into her "cool lingo" conversation, and i hate disappointing people. please help me to not make a social blunder. Btw the pic is of taylor swift labeled as "my baby." please no comments about T.S. or i will have to hunt u down and pleasure my self in ur ear. THANKS YALL
