One of the greatest days in history. The day the boomhound was created. Falls on the 6th of April every year.
People take out their boomhounds and brutalise their women with them.
1. Guy 1: What are you doing for boomhound day this year?
Guy 2: Same as every year, I will brutalise my woman with it!

2. Girl 1: Wot did Charlie get you for boomhound day this year?
Girl 2: A broken throat and some very sore orifices.
