Drinking soda non-stop. I can drain a 2-liter bottle of Sprite in 10 minutes. Not really an addiction because I don't have 'cravings' for soda, but I do like it : ).
Alt, that's one bad habit. Unfortunately, there are to many stupid people in this world. It's almost a syndrome to be intelligent how many stupid people there are.
Biting my nails is my worst habit, My second worst habit would probably have to be scratching a certain body part and then smelling it...
i knew a really freaking hot chick that would just do that in front of people like it was nothing... so nasty lol... i would have tried to date her if it wasnt for that lol...
my worst habit is... um biting my nails and i also dont floss everyday... i brush everyday but not floss
