Is it appropriate for a guy to call a girl 'dude'?

No, how about calling her by her given name?

There's an idea.

Out of all the nice things to be called, you get called dude...it would irritate me but not necessarily a turn off. Unless it's constant. That's a whole different story then lol

hahahahahahaha i think its the lamest thing when guys call a girl "dudette" allllllll my friends, even girl friends, call me dude. its like a second name.

so really it just depends on the girl. some girls hate it, along with "chick" so just be careful. u don't wanna get a slap in the face or something

dude works fine. dudette actually sounds really retarded to me. no offense or anything. dont over do it though. but my friends and i use dude on each other all the time. so just say watever comes.

it depends on the person some women get offended, i call my guy friends dude and female friends chick

personally if a guy said that to me (or even a girl) i would be annoyed

it's just one of my pet peeves! i hate the word dude

No, do not call a girl "dude". Expand your vocabulary.

It sounds rude.Girls won't like any guy that can't tell them apart from a boy.

watch this! dude! http://www.youtube.com/watch?v=67EvAeU1mxY&NR=1
