Monty Python is great.
A really embarrassing word is Wanker.
Just rewatched “Beatles 1964” which is a new documentary based on the original footage shot by the Maysle brothers. They had basically unlimited access to the Beatles from their arrival flight until departure from Miami two weeks later.
In one scene Murray the K (who comes across as an annoying loudmouth) called their song “Love You Do” instead of “Love Me Do.”
John corrects him but you can tell he knows Murray is just a jerk opportunist. After a few joking exchanges John calls him a Wanker. Murray, obviously unfamiliar with Brit slang hops right on it and calls himself “Murray the Wanker.”
