Fat **** can't run! Their thighs rub together which if sustained can cause the ***** to spontaneously combust and as you can imagine with all that fat packed on - the little fucker will go up and stay lit for quite some time. Probably long enough for a homeless ex-banker and his ****** to gather around for the night to stay warm.
No, I'm guessing this is an image of the fat *** falling on his face. Which is always a sad, pathetic, hilarious sight to see.
