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.”
