SIYM

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)!

Siyma is the most hottest girl ever it will be hard for a man to steal her heart. She is very caring, kind hearted and loving. Siyma is always up at night because of her children and is always looking out for people. She is also always keeping warm when cooking she would wear her Barth robe during winter. If you have a Siyma never loose her and never break her heart keep her with you forever.

Siyma is the hottest lady ever!
Siyma has a big bum I wish I could have it!
