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.”

A person who usually has Facebook, will laugh at memes or jokes that are usually not funny. These people will also tend to call millienials, boomers. These people also have a very low knowledge of meme culture and will not find a meme today that's funny, funny or humourous because of their lack of meme knowledge. Boomers will also laugh at minion memes or memes from 2011 to 2017.
"Hey Josue, that 20th century fox intro with an off key recorder playing in the background was not funny. You do realize that's pretty old right, it's not very funny anymore." "Ok Boomer, you're over here laughing at Obama memes."
