Boomers are old people that are really cringeworthy. They are often people that are old, above 60, that use computers and laugh to jokes like someone that is getting shorter because he is looking at his iPad too much so his spine is broken. A boomer can be a person that is old and just stupid, like having down syndrome :)
Boomer: Ahahahahahah, look at this meme that says: iF sTrEss burned calories, I'd be a model.
Other people: What is this boomer
