Mystery Hip Hop/Rap Song

I heard this song on the radio - actually I always hear it.
It's a hip-hop, rap type song with a male singing.

The lyrics are:

"if your *** is bigger than your waist and you got a cute face you gotta sexy body"

There's a female in this song too - she sings the "sexy body" part

If anyone knows this song, I'd REALLY appreciate it! I've been looking for it for awhile!

Thanks!!

I actually heard that song tonight but it was a remix with Young Burg. The lyrics from the original song
"if your *** is bigger than your waist, and ya got a cute face, you got a (female voice in one version, reggae artist Sasha) sexy body"

In the version with the Sasha the title of the song is Coca Cola Shape (Dat Sexy Body Remix) and it features Fatman Scoop, I think this is the one your looking for

There is also another version, im pretty sure its the original and its by Fat Man Scoop feat. Elephantman and Jabba. The title is U Sexy Girl
