TMUBA

"Tits Magee Untouchable Brigade Of Awful" - a gang of cosmetically-enhanced women you see at every Los Angeles audition who, rather than knowing the script, yap about going to a yoga class where they see celebrities, breast implants, Rodeo Drive, and other meaningless things. They don't really want to be actors, they want to be famous.

They are "untouchable" because despite looking like mannequin porn stars, you should never ever date these women.
