I’m not a fan of the terminology myself, but I get it that when someone says Boomer Shooter, they don’t mean “Shooter that plays like DOOM/90s shooters which would have been played by someone born between 1946–1964.” (which they largely weren’t)

They simply mean “Boomer = old” as in “old and/or inspired by old 90s shooters i.e. DOOM and the subsequent DOOM clones.”

It helps that it sort of rhymes / rolls of the tongue.
