Boy troubles

This guy randomly snapchatted (Sbarnett30127) and we talked he's one of my brothers old friends...he's a freshman in college this fall and I'm a freshman in high school...we were talking about how I wish I had a car so I could go get food and he said he'd take me, I politely said no, but we were talking about how if I had a boyfriend I could eat more than him (Aka future boyfriend whoever where ever he is) and Brandyn (this guy) was like.."I don't know I could eat more than you) and he's been snapchatting me non stop..what is this.
