Wickedly awesome. Like that girl from high school that everyone got along with. Or your really good female friend who's been to hell and back with you and still can make you feel good with a compliment when you need it and/or a kick in the ass when you deserve it. Awesome person who'll rock your world.

Your new girl's pretty casstastic, dude.
