If I like the look of a girl, I'll say she's hot. If I like the look of a guy, I'll say he's cute. This never ever varies.

If I dislike a person, I use the term "asshole" (yes, even though I'm british) or "c***", and am not particularly inventive unless I want to pick at a particular quality (like when I called someone stupid by saying he thought "irony" was something you did to your clothes... long story)

So I'm not very articulate when it comes to describing other people really.
