"Simp" (from "simpleton") was popular in America in the '20s and '30s but never went away completely. I guess it's making a comeback.

"Grok," from Heinlein's 1961 novel, had something of a vogue in the flower-child '60s, and likewise has never gone away.

"Woke," by the way, now means "politically awakened or enlightened to matters like racism, inequality, oppression, etc."
