Boomers are people from older generations that don't give a fuck about what we do nowaday and make you repeat THEIR childhood or whatever. They also don't know our language very well for example, they have no idea of the concept of slang. Long story short: Adults and older people don't know what we do and don't understand what we normally do in our daily lives.
