Is this a red flag?

A guy i've matched on CMB sent "bb i've eaten :D" to me which i happened to see in my message preview. I assumed the message wasn't meant for me since he deleted it within seconds and we are definitely not at the stage where we'll call each other "baby". We have our first meetup scheduled next week and i'm skeptical if i should still continue meeting him after this since i'm pretty sure people don't call random people "baby"?
