Je me sens bouboule

There have been recent reports in the news that the French population might be getting fatter. A quick look at my waistline and the pants button I recently caused to implode by just getting near it seems to confirm this.
So, as a follow-up to a previous post today's word is:
bouboule (pronounced boo-bool) = fatty

Can also be a (not-so-nice) nickname
Hé bouboule! = Hey fatty!
