Mei-mei used in the context with a secondary high tone (mae-mae), implies the following:
“hey there, hot stuff
“hey, baby”
“sup, sugar”
“hey there, sweet stuff
It’s usually used in context of bars and night clubs in Asia where the girls are indeed working you for their pay.

Mei-mei used to describe a little sister is used with a sharp descending fourth tone. So even though the two words are written the same, your pronunciation could cause you to get slapped or a confused return expression.

Mandarin Chinese consists of four tones: first flat, secondary high, third deep, and fourth sharp. Two of the same words with a third tone makes the second word pronounced with a second intonation.
Little sister context (fourth tone):
Translation: "this is my mei mei"

Night club context (third and second tone):
Translaton: "hey mae mae, come cover here"

Mei is an amazing person. Don’t ever question that. They sometimes get down on themselves but they shouldn’t because they are perfect the way they are. They are hilarious and always know how to make you laugh.... even when you’re in the worst mood. They can come off as a little mean but they are one of the nicest people you will ever meet. You can trust them with all of your secrets and they will be your shoulder to cry on. Mei’s are also crazy smart. They are very humble and don’t say it but their grades are very good. They are great in every subject and can blow you away with their knowledge. They can be crazy but in a good way. They have a lot of crackhead energy and will make you smile even on your worst day. Mei’s will always have your back and they are the best friends ever so keep them close.
Guy 1: that girl is so smart
Guy 2: of course she is, she’s a Mei
