fuck with your parents day - 12th Jan

definition: do whatever you want that your parents don't like
e.g. play music loudly, stay up late, wear clothes they don't like, buy something you've been wanting to for ages but your parents wouldn't approve (torn jeans), yell at them from another room :)

Me: Karen, it's fuck with your parents day, what are you going to do?#
Karen: what's that?
Me: fuck with your parents day - 12th Jan, is doing something your parents don't want you to do
Karen: not talk to the manager >:c
