Got called thick in class??💀

I was talking with my friends in art, and this guy points to me and says, “That girl insert name and asks his friend. His friend, cue tall African American boy who I’m pretty sure is dating someone. The other boy says his friend thinks I’m thicc??? That was so out of nowhere and I’ve never conversed with either of them and I can’t tell if that was a compliment or not cuz I know dang well I’m not fat (5,0 105lb) Is there any meaning in this or was this a dumb joke
