A pretty girl is entirely different than a pretty boy.
A movie, a quote, a boy, a shirt or a song can be cute for a girl. If a guy calls his friend's shirt "cute," either he's gay or his friend's shirt is.
Lately I've been noticing a lot more of this kind of phenomenon. (Simply because I've been noticing it, not because it is suddenly more prevalent, I'm sure.) And I find it really interesting, how the gender of the speaker, or the gender of the person being spoken about, can change the meaning of a word completely.
Think you guys could muster up more examples of this?
