BAG day 

"Buy A Gun day" April 15th...tax day. Conceived by gun bloggers in an effort to encourage gun ownership and to demonstrate the strength of the US gun owners by suggesting that everyone buy a gun (ostensibly with their tax return) on April 15th every year.

I bought a .45 for my BAG day gun this year.

Bad bag day 

Those days when your handbag is so messy that you are scared someone you don't know will accidentlily notice and think that you are a total mess.

God, I hope I am not in a car accident today. I have such a bad bag day

garbage bag day

In sports, a day when multiple players are dismissed from a team, who at least symbolically - or even actually - load garbage bags with their locker belongings. A sorrowful event.

Today once again is garbage bag day, with the exodus of many preseason hopefuls who didn't survive the final cut from NFL football teams.

That group of gutter punks on the corner just smelled like a bag of day old dicks when we walked by.

Yesterday we talked about bags of dicks for 12 hours straight until the bag of dicks grew to be a bag of day old dicks.
