Basically, she hates all the bitches.

TMZ obtained a snippet of her upcoming single, "These Heaux" (pronounced "Hoes") -- which contains the following lyrics:

"These hoes be lackin', see me in back and ... they talk all this sh*t but don't say it in person."

"Water, water drippin', come take a peek ... you in a trailer ho, bitch you can't compete."

She also brags about sippin' lean, riding in a Maybach and being able to keep a man.

By the way, she's dead serious about her rap career and even picked a rap name -- "Bhad Bhabie."

It's pronounced baby ... no offense to Barbie and her crew.
