Wanker was an invective often hurled at Ted Lasso, starting with his very first press conference at AFC Richmond. Many of Richmond's supporters said to him, even in front of his wife and kid. They did so to induce their profound displeasure with his publicly stated lack of knowledge about football.
The first Briton who defined the word was Mae, who warned Ted not to let the fans call him a wanker. She said it was "bad" and then indicated through hand gestures that it was someone who masturbated.
When his son finally asked what a wanker was, Ted picked what was probably the very most positive description, saying that it was "a man who likes to be alone with his thoughts".
