We eat each other whenever we at the dinner table
The primary meaning of this line is to highlight the tension in the relationship between the protagonist (Weezy) and his girl. To “eat [at] each other” in this context means to fight viciously. Even when sitting down for a nice dinner, they can’t help but argue and attack each other.
But it’s also a double entendre––"eat each other" as engaging in oral sex. This particular meal is a favorite of Weezy’s.
