July 17 is the international day of slapping your GF's sexy ass. You can slap her ass as many times as you like and if she doesn't let you slap her ass you should find somebody else because slapping your girl's sexy ass is a must in a relationship.
Me : "Hey babe do you know what day it is ?"
GF : "No, what day is it ? "
Me : "It is July 17 that means that it's international day of slapping your GF's sexy ass !"
GF : "International day of what ?"
Me : *slaps her sexy ass*
GF : *smiles*
Get the July 17 mug.
