All people blush.
usually because they all find something intriging about guy, but I doubt if all college girls blush at random when they see a guy, unless of course they like him.
LOL well it obviously means that she likes him. Girls typically blush when they like a guy.
It means that your good with girls/women. KEEP UP THE GOOD WORK!
It means that the guy is cute and the girls wish to be with him
it means that they fancy him
The girl likes that guy or finds him attractive.
They are crushing on you big time
They love him
They like you, appreciate the attention while it lasts
they like you and ask them out and they will say yes
Some do, some do not
Girls tend to blush around guys they like.
