"Whoa, check out that dudegirl!"
by Girly February 10, 2005
a girl who is cool enough to hang with the fellas and girl enough to hang with the girls. she likes sports, action movies and chick flicks. she eats wings and doesn't like purses. she is a heck-of-a man and good woman. dude-girl is awesome fun to be around.
Sidney is coming over to watch football and she is bringing pizza, she is such a dude-girl.
