A monolithic milf in a league of her own, by whom all other milfs shall be measured. Attained by a female after having naturally birthed at least 3 or more children and still able to maintain a face, figure and demeanour that draws much attention from the opposite sex. Age range irrelevant; any woman capable of this feat deserves kudos over and above the standard milf.

#2:"Hell no, can't be. She's the babysitter"
#1:"Dude-- those kids just called her mommy"
#2: "Damn, she can mommy me!!"
#1:"Dude, she's wearing a red thong under 'em jeans!!"
#2:"Hell, that ain't no milf... thassa Megamilf, indeed."
