Does eye contact mean anything from a guys perspective?

1.) So a guy I know stares at a girl when they’re sitting in a group chilling not doing anything and he’s staring at me.

2.) And when I was eating pizza and he kept staring at me (even when I wasn’t paying attention and was doing something else or talking to someone) but I noticed he was sitting opposite me and staring and I looked up and smiled and he smiled then I was like why u staring lol and he was like no reason.

3.) And I was standing with him outside a house waiting for a friend and he was eating something while we were waiting and while he was eating it he kept looking at me and making eye contact when he was eating (kinda like how a girl would make eye contact when eating a banana or a hotdog lol) so I thought that was weird and then he stopped eating and stood there looking at me and I maintained eye contact this time so we stayed like that and he smirked.

Is that normal? Because he’s just a fiend and I don't know I’ve never had a friend be gazing like this before. so what does eye contact mean to guys?
