A, sometimes big, but flat and disgustingly sagging ass. Normally while fat black women just plain have big, round asses, most overweight white women tend to have pancake asses. Sick.
Reggie: Ewww, Tommy, we saw you hittin' on that pancake ass bitch outside the club last night, what's gotten into you fool?
Tommy: Shut up and pass the syrup.
Does not apply to just women, many men have flat ass too. Have you seen the amount of them who have their belts under their ass? Insufficient buttocks to hold them up.
