Drunken kiss on cheek?

If a really hot guy who has pretty much never spoken to you before runs into you at a party and tipsily/drunkenly (?) says "hi [name]!" and pulls you into a hug and kisses you on the cheek (in front of your stunned roommate)...but then barely talks to you at other events after that...?

Explanations welcome. Thanks!
