Mine is crisps and anything related like tacos. I just eat a whole family pack at one go. The worst is when I'm reading and eating at the same time. I seem to have gotten in the habit of holding a book with one hand and feeding myself crisps with the other.
Now I have rolls of flab around the middle (yukkity yuk) and I'm shaped like a barrel. I think my waist is about the same measurement as my chest!
Ugh! Yuk! GRRRRRRRRRRRRRRRRRRRRRR
