Mrs Crumplebottom 

Named for a character from the Sims video game, Mrs Crumplebottom is a prude and a killjoy who has no social life, and dislikes seeing public displays of affection.

In the Sims game, Mrs Crumplebottom regularly purse-whips and/or lectures other sims who kiss or make out in public.

Don't be a Mrs Crumplebottom.

Mrs. Crumplebottom 

Someone who is opposed to PDA, nudity and the like, as well as having many old-fashioned ideas and views and dressing up in Victorian style clothes.
Named after a character in The Sims franchise with the same mannerisms.

Mrs. Crumplebottom totally interrupted our date and hit me with her purse!
