I know this sounds lame, but trust me I find this 'cute' word so very unpredictable. At least guys are articulate and scream "Phew she is hot!" on seeing a hot chick. Girls always bug about the 'cute' factor. For example a friend of mine that day exclaimed on seeing a guy "wow he's cute" and I was like-"excuse me !..him?"
I know its a silly query but just throw light on this "cute" thing.
it could probably mean quite a few different things depending on the girl. I usually use it when I see a guy who's goodlooking but not like 'sexy' I guess. I also use it when I see a guy that has a baby face or really soft features.
If I say that a guy who is younger than me is cute, I mean the cute as in baby cute like "aww that baby is soo cute." If I say that a guy who is older than me is cute, I mean that he is absolutely gorgeous and handsome and I want to get to know him. But that's just me. Other girls will probably have different views.
