The word "embiggen" first appeared on The Simpsons in the "Lisa the Iconoclast" episode, as did the cromulent word "cromulent". For some reason, wertperch neglected to add this word when talking about LieQuest 2022, but he did remember to add in cromulent and modren.
In more recent times, the word "embiggen" appeared in the last book of the Harry Potter series (#8), "Harry Potter and the Curse of his Internet History". Only the most die-hard fans of Harry Potter sought out the last novel by J.K. Rowling dealing with the (now) middle-aged wizard. Stuck in a dead-end job at the Ministry of Magic in the Auror department, Harry has been working exceptionally long hours tracking down wayward witches using magic to get muggles to sign up for their naughty Only Fans pages. His wife, Ginny, is having an affair with Harry's cousin, Dudley Dursley.
When Harry gets a call to intercept another magical person using their skills to enslave thirsty muggles at a notorious strip club run by Draco Malfoy, he discovers his old nerdy and weird friend, Luna, freshly divorced but still keeping her married last name as Luna Longbottom. It turns out she's now a multi-millionaire because of her exceptional financial and investing skills, but she still enjoys getting chased by hot humans and the occasional centaur.
She promises to retire if Harry will let her off the hook, and also decides to teach him a forbidden magical spell called "embiggen".
Not wanting to toss his old friend into Azkaban, Harry agrees. The added bonus is that he can use this secret spell to enlarge his throbbing purple-helmeted warrior to epic proportions and win back the love of his estranged wife.
Harry goes back to his home, #5 Privet Drive in Little Whinging, and performs the spell. Unfortunately, he mispronounces the spell as "embigly" and the ghost of famous comic and impressionist Rich Little becomes embedded in Harry's delicate parts. Even worse, the ghost is stuck doing loud impressions of Donald Trump. No matter what he does, Harry cannot get his trouser zipper region to stop muttering about covfefe and non-politically correct topics.
The book ends with Harry at St. Mungo's Hospital for Magical Maladies and Injuries, checking in to a room next to his old instructor, Gilderoy Lockhart. Due to the book not selling more than fourteen copies, there is no current (as of the date of this node) publication date for book nine scheduled. At no point does Harry's internet history get mentioned.
