It is kinda derived from anime, and it conveys a different thing depending on the situation, could be mischievous, could be grateful or something you do when you say your welcome, could be when your boasting happily, could be when you're asking some neutral question ostensibly but have a hidden agenda or special interest (kinda why I was doing it- I was asking if you had it with the hope that that would mean I get it too). Its just a cuteness thing to a lot of people. Its taken on a lot of meanings, hard to explain, and so on.
