Cus is just a shortened version of the word BECAUSE. It's often used in song writing/singing, simply for the fact that it flows better and is much easier to sing.

Sour stomach is just another phrase for acid indigestion and is a stomachache like condition. It's when there is excess buildup of acid in the digestive track and esophagus, which can cause heartburn or acid reflux.
Eating tons of fatty foods before bed can cause you to have a sour stomach.
