Whats up with this guy?

ok so there's this guy in my class lets call him eli. Eli and I are kinda like enemies its weird. but anyways he's always listing in on my conversations and making comments on them then hell just say random things to me all the time and he gave me this dumb nickname wich is weird because he never gives anyione nicknames. Then if I'm ever talking to other guys in my class hell like run up and join the conversation even if he was talking to someone else.
