Notes:

This meme is referencing coming across an NPC in Fallout Las Vegas which is passingly referred to as a Boomer, possibly a historical reference the Oklahoma Boomers which were the people who settled the land about a decade before the Sooners as seeming the suffix ERS was common back in those days. The Doge pointing the weapon in the meme is a typical type of theme with ironic dog memes and is just funny now because of the popularity of hte OK Boomer meme.
