Those who think they can drink a lot, end up drinking too much and puke their guts out resembling a boomer from the Left 4 Dead video games series where a boomer pukes on players.
Holy shit! I can't believe Brandon drank that much! He looked like a total boomer when he was puking his guts out!

Get the boomermug. Some annoying ass old person who thinks they’re the only person alive/thinks they should have it their way because they’re old.
Old person: “It’s not nice to stare at your elders.”
Then stares at a young adult because they have piercings or/and colored hair
Young adult/Teen: “Okay boomer.”

Get the boomermug. Boomeritis is an illness that forces the infected to talk like old British men from the 1800’s. It can be fatal in some situations, but the worst cases tend to only cause lasting damage to the brain and how it functions.
