How would you go about doing this? Making a skinny guy look fat...

well, bubble wrap does good. fold it up length ways and use to create folds of flab. start at belt and work up. create two large tits and, a little padding under arms.

spray water under arms for extra fat person lookingness.

i did this, and i looked exceedingly fat.

should have got pic, but they do it in jackass.

yeah bubble wrap is great but make sure that you dont let your t-shirt go upwards to show the bubble wrap. Also it doesnt work on your legs very well.

Layer your clothes.Like wear lots of sweat shirts then wear a coat, and stuff like that.

another worthy point is it's helluva hot, i was wanderin around in aberdeen (scotland) at about 4 degrees celsius wearing nothing but my bubble wrap, jeans and t shirt. i was roasting.

Why would you want to make yourself look fat?
