Yelderly 

Elderly of age, but still young in thinking and physical activities.

My age exceeds 65 yrs, but I jog everyday, workout 3 days a week and teach ballroom dancing. I consider myself yelderly!

To be young, most likely a Millennial, but complain as if they are not of this generation and go against social fads.

I'm sorry, am I interrupting your grind session? I'm sorry, I'll let you sink back into your phones. I hate my generation...what do you mean I'm yellderly?!

A young person who complains that something today is bad and that it was better in the "Good old days" even if they have never actually experienced the alternative.

Jacob: Kids these days can't stop looking at their phones, it was way better back in the 90's.
David: Jacob, you never lived in the 90's, stop being so yellderly
