friend who feeds you

Theres always this one motherfucker in the friend group that never eats enough and never brings food to uni or school and then theres the mom of the group that always feeds you and keeps up with how much the motherfucker eats. They will always have a snack with them e.g. mentos and feed you proper meals, like pizza.

Sarah is my friend who feeds me and if you become friends with her, she will be the friend who feeds you.

Sarah always has mentos on her, you can count on her as a friend who feeds you
