when someone (A boomer) is so determined to live like they are in the 1900's that they force they're family to live like: women in the kitchen, men outside working or some shit and kids playing with toys and riding they're bikes or something.
person A: my dad is so much of a boomer + he wants me to actually live like I am in the 1970's.
person B: damn those species are rare.
A boomer, (usually a parent), who tries to force their outdated, ineffective, ignorant, offensive, stupid and/or absurd values onto the next generation
"My mum told me to get a credit card and just spend money to prove to the bank I can pay it back. She is such a 'Boomer groomer'."
