Does he like me or is he just being playful?

Ok im 15 and a sophmore woop woop well my brother is 17 and still rides the bus with his friend who is a senior(pooba)…well on the bus rides home Pooba would like play with my hair (kinda like hit it or swoosh it) then a long time ago I called him a chinc and he didnt get offended or anything so then everytime I saw him I would say HEY CHINC! then sum how he switched it on me and now im the chinc…but it seems to me that when im listening to my Cd player on the bus he’ll say sumthing about me like “yeah ME does it with bunnies” (just playing around) or sumtimes he’ll do a voice that will make me laugh or like the other day he took my cd and I had no clue he had it til he was singing my songs.I think he does it to get my attention(just my opion)

I have a trampoline in my back yard and today I went outside to practice front handsprings and I was trying to get my dog to get off me and Pooba was at the other end of the yard calling me a chinc and turning to walk down the street with my brother.

Im not sure if hes being playful with me or if he likes me. Hes ~CoNfUsInG~ me! HELP!.
