Why did my crush call me mama?

We met in a class and managed to become friends. He ALWAYS wants to make plans to hang out. Usually though he will say "lets all" so it seems like he wants a group thing.

Mid convo I was asking him a question and he goes "yes mama".

Do i give motherly vibes? OR is that flirting? I really can't think of situations for what else it could mean.
