Not really. That can mean that he is slightly interested but it can also be that he is really friendly and like he wanted to smile. You can only know if he likes you if you ask him. If you have a realtionship than yes but maybe he's just being nice, but look for the signs! :)
If he smiles at you and gives you hints that he likes you then yes. and no it would not mean that you are sexy it just means that he is attracted to you now if you get like 10 dudes to do that to you in like 2 hours then yes you are sexy!
He could just be being friendly, but the more likely thing is that he likes you.
=D is a cheesy grin :)
Yes. It can mean: - like cheese in taste, smell, or consistency : a pungent, cheesy sauce. - cheap, unpleasant, or blatantly inauthentic : a big cheesy grin / cheesy motel rooms
she likes you alot
Started smiling, probably used like "Cracked a smile", when the person "cracking a grin" smiles, even though you wouldn't expect it.
That doesn't always mean she likes you, but she might be interested.
He likes you ! :)
It means he likes you but it depends if he smiles when he says it.
he likes you or he thinks your hot
yes..
Not necessarily, but if he asks you out or something, then definitely.
he looks at you a lot and he smiles at you.
It means she likes you!
