Refering to the group of kids from Hoover,Alabama who anually take a glorious ride down the beautiful Cahaba river with cigs, beer and vodka in hand. it consists of 2 champs AKA wrestlers..2 soccer pussys and one shitty baseball player. Every year the group grows which usually ruins the sanctity of the whole trip but its fine..the cahaba river rats will live on forever.
person 1: Did you see those fresh looking kids floating down the Cahaba this morning?

person 2: probley those old Cahaba river rats

Person 3: yeah, you can hear them at all hours of the night screaming "Cahaba!!!" "what?!?!" "Cahaba Riverrrr!!!"
