I don't like to be called a "Baby Boomer." I prefer "Geezer." One is a Boomer simply because of date of birth. One must earn the title Geezer by attitude and outlook, as well as age.
The modern meaning of geezer is “an eccentric (unconventional and slightly strange) or irritable (easily annoyed) old man.” That’s me in a nutshell, and proudly so.
