100 bands, cut your girl, now your girl need a bandaid
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”.
“Bandaid” 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 bandaid. (But it’s all good, because he’s got 100 bands.)
