fatten up
Put meat on
To fatten up is to make or become fatter, typically through deliberate feeding: We're fattening up the turkeys for Thanksgiving.
The phrase often implies preparation for a purpose—animals for slaughter, a thin person for health.
Figuratively, to fatten up an offer or account is to make it more substantial: They fattened up the severance package to avoid a lawsuit.
