(Red nose my bad broad)
Continuing the wordplay from Q’s line, ASAP has a bad bitch (in this case, most likely a redbone) with him. A bitch can also refer to a dog. Red nose pitbulls are a popular breed. .
ASAP is possibly stating his bitch has a coke habit, as this can lead to nosebleeds, and if she’s white, she’ll have a red nose from the irritation snorting things causes.
