On June 9th it is considered to be National Kiss Your Step Sister Day. On this day it is highly recommended that you make out with your step sister. Any other day it would be considered incest, but on June 9th it is encouraged!
Person 1: Bro on June 9th you gotta make out with your step sister.

Person 1: Cuz it’s National Kiss Your Step Sister Day, duh.

Commonly used as an excuse to get out of something you can't do and or when you previously had accepted a invitation to something but need to get out of it.

Can be embellished with descriptive addiction as such as ...for a family do or to go watch a football match.
