Quislennial 

Combination of Quisling and Millennial. A self-hating Millennial who goes out of their way to bash their own generation, often in a misguided attempt at winning the approval of older generations who loathe them, or show that they're "not like all the others".

Joe's such a Quislennial, acting so smug and superior just because he toadies up to those fucking Boomers.
