I had to look it up because I thought it was about "making boom and shoot".

Also it's a bit weird because I don't know any boomer who played a shooter. Actually I don't think I know any boomer who played video games, others than mobile word games.

The only people I know who played shooters in the 90's were Gen X kids like me.

Anyway, I guess I'm a grumpy old man now but it's a bit annoying that "boomer" has become synonym with "old people" and "millennial" with young people, while Gen X are close to retirement and millennials are clearly no longer young.
