Large, bulbous fatty deposits just below the shoulder and armpit area. Usually (but not exclusively) located on a person's back.
Darla is a whole lotta woman. I gave her a hug and found myself with a coupla handfuls of pit tits.
Fat or flesh that can't be classified as back fat or actual breast tissue that hangs under the arms. They are the counterpart to Bingo Wings, the excess fat or sagging skin
on the upper arms. When not compressed by the bra of a band or other "foundation garment", excessive pit tits can prevent the owner from drawing their arms to their ides, giving them a sumo wrestler stance.
I wish it were possible to moosh my pit tits into the cups of my bra. Maybe then, I wouldn't need a wonderbra just to look proportionate.
