100 bands, cut your girl, now your girl need a Band-Aid
100 bands = $100,000, otherwise known as a hundred stacks.
“Cut” is slang for “having sex”, so he slept with your girl. The band aid is a play on the use of the word “cut”.
“Band-Aid” also ties back to the “100 bands” he mentioned. 2 Chainz is saying that now that he’s had sex with your girl, or cut her, he will likely buy her something, give her a Band-Aid. (But it’s all good, because he’s got 100 bands.)
It’s worth mentioning that 100 bands is a lot of dollar bills. If someone were throwing that many bills at a girl, she could easily get a paper cut.
Alternatively, “cut,” in its more common usage, can mean to dismiss or relieve of duty (as in, “cut from the team”, so this lyric could mean that this girl has been “cut off,” and, where before she was supported by 2 Chainz with his many bands, now that he has left her, she is going to need a “band aid,” or a new sugar daddy.
