Firstly, when a girl’s momma thinks you ain’t shit, that DOES sting like a motherfucker. in the line after that, he plays on the expression “the apple doesn’t fall far from the tree.” Which refers to how a child is similar in character to their parent. In this case, what he’s trying to ask is if her momma ain’t feeling him, does it mean that she ain’t feeling him either?

Even though he puts on a front, he realizes that the drama he goes through with his girl is what makes their relationship so exciting, comparing the taste of their love to “filet mignon” (that really is some delicious shit).
Also, he compares her pussy to a meal that he’s taking home to finish off, eating it up… or beating it up, which is weird if you’re still thinking about it as food.

A clever use of the phrases “swallowed my pride” and “ate my words”: first he had to put his pride away to apologize, and then took back the words he said; a wholesome meal of guilt that will leave you with the “you-ate-ass face”.
