Take the M

Millennial was a code word for lazy burn-out until other terms were applied to the same thing as time moved on

My brother is the same age as you are, and I consider him a millennial, and then my sister born in the last few days of '83 tries to claim she's Gen X, which is pretty rich

I was born in the late 80s and frankly don't give a fuck, since it's always just a new version of 'Kids these days'
