fatty 

Me, I eat too much (so far today 2/3s of a large chocolate cake, 1 tube of pringles with dip, 2 pancakes and half a tub of Ben and Jerry's - and it's only 11am!) never exercise and am proud to show off my 250lbs in a bikini in summer. Watch out world we're taking over!

Fatties are everywhere
