Definition & Meaning of "wankerish"in English

What is the origin of the term "wankerish" and how is it used?

"Wankerish" is a British slang adjective that emerged in the late 20th century, derived from "wanker" (a vulgar term for a foolish, obnoxious, or contemptible person) with the suffix "-ish" to describe behavior or qualities resembling a wanker. It characterizes someone acting in an obnoxious, self-important, or idiotic manner. The term is primarily used in informal speech, online commentary, and humorous or critical writing. It is clearly derogatory and mildly vulgar, intended to criticize or mock, and rarely, if ever, used in a neutral context.
