look up any word, like pussy:
World Ex Day is on 11th January.It's an annual event. On this day all you do is just call your ex and say “happy world ex day”. And it’s not just about your ex relationships but also it could be about your ex colleague, ex client, ex coach, ex best friend.
There is a group on facebook as well.
To ex girlfriend: hey, happy world ex day.how have you been?

To ex boyfriend: hey jerk, happy world ex day.
