repletion \rih-PLEE-shun\ (noun) - 1 : The condition of being completely filled or supplied. 2 : Excessive fullness, as from overeating.
"Belly distended, waistline bursting, eyes glazed with repletion, Albert picked listlessly at his teeth with a fork while savoring another meal well-prepared and enjoyed."
Repletion is derived from Latin replere, "to fill again, to fill up," from re- + plere, " to fill." Plenty is a related word.
