Drinking (sugar filled drinks)
Dangerous driving (fast & furious style)
Falling asleep on public transports
Picking on your Mother-in-Law
Having pointless "one night stands"
Wearing a bra... (ladies only, please)
Getting late (for everything, all the time)
Spending more money then you should (or have)
Scratching your "naughty bits" in public
Being wrong too many times
