Ok so get one die and roll it. Take the number you get and times it by your age. The result you get you must give yourself a wedgie at least once a day for that many days.
Example: If you are 20 and you get a 2, then you must give yourself a wedgie once a day for the next 40 days.
Sorry if this is hard to follow, I get lazy when I'm posting using a phone.
Take care! Oh and feel free to comment how many days you ended up with.
