He called me his side bae.. what does that mean?

lostandlonley
So me and this guys has been friends for about 3 months now and we've been becoming pretty close as friends. I don't have any feelings for him or anything, and he has a girlfriend, but for the past month when we do group hangs and stuff so We been hanging out a lot lately almost every other day, and for about 5-6 hrs a day. And he would do certain things such as holding my bag, putting his arms around me, hugging me for no reason, calling me babe and stuff that my boyfriend would do. I find it kinda awkward, but I just let it slide, but resently he called me his "side bae" which has been really annoying me, cuz ain't no budy wanna anyones side bae. What does it mean tho?

by the way I have a boyfriend... and if anything I see my friend more as a brother to me. This just makes things so awkward. What should I do?
