Yes it is used "here". The consensus here is that is the moniker of the X/Millie cusp.
GenX is a generation , "here".
Y is the designated moniker of the X/Millie cusp.
The consensus "here" is wrong. The general usage is correct. A generation cannot have two conflicting names.
I know of nobody here that designates Jonesers or Y'er as a generation, but a transition or if you will , an inflection point where one generation transitions into another. It's all a POV. If one is of the mind that generations are discrete/binary entities, then yeah, no such thing as a Joneser or a Yer. OTOH, if one considers generations as analogue then cusps as defined ash such: (a transition/inflection) set of cohorts that mark the transition from one generation to another. Rationales: regional differences when turnings hit, upbringing, rural vs. urban, etc. Take the year set of (1952,1962,1972 (
obligatory winky for Vandal), 1982(
oblgitory winky for JohnMc),1992) you get a nice core/cusp/core/cusp/core.
