South In Your Mouth.

Unofficial Battle Cry for University of South Alabama athletics. Literally means "in your face," but since "mouth" rhymes with "South," the chant is "South in your mouth."

Has been in use by students and fans of South Alabama sports since around 2001.
Goooooooooo JAGS! U-S-A! South in Your Mouth (SIYM)!
