What's the name of that song?

There's a song that I haven't heard in like 3 years! but... I know that two brothers sang it and their names were like Jared and David or something like that... and the song was called like "C_____ Girl". all i know is the first word started with a C (i think!) and the last word is "girl" and I think it said the name "stacey" in the song a lot.! Thank you so much! It's driving me crazy that i cant think of the name! I want to put it on my ipod! Thanks sooo much!
