I really just have to summarize Thomas's entire life:

He was in a committed relationship with a male swan named Henry for 18-24 years before a female swan named Henrietta showed up and mated with Henry.

Thomas was initially jealous of the pair and attacked them, breaking 2 of the 5 eggs Henrietta had laid. However, once the remaining eggs hatched, Thomas warmed up to them and helped raise them.

Henry couldn't fly because of an injured wing, so Thomas taught the cygnets how to fly.

When they needed to reduce the goose population in the pond where Thomas and the swans lived, they dyed Thomas's feathers red so he wouldn't be separated from Henry.

Henry, Henrietta, and Thomas remained in their happy throuple for years and raised 68 cygnets before Henry died in 2009. After Henry's death, Henrietta found another swan and flew away, leaving Thomas alone.

Thomas finally met and mated with a female goose in 2011 and had his own babies. However, another goose named George stole them and raised them himself.

As Thomas grew elderly and blind, he was relocated to a wildlife center where he raised orphaned cygnets.

His caretaker at the center described him as "pretty high maintenance."

Thomas died in 2018 at the age of around 40. He had a funeral that included a small coffin and a procession that was led by a bagpiper. He was buried under the stone where Henry was buried, the two finally reunited in death.

Also a lot of early 20th century vulgarity is recorded in Letter from My Father, which is a collection of letters published by a man who's dad was, in short, a major slut and human disaster who wrote about his sex life for his son. It's insane. You can find copies of it online & it's a wild fucking read (literally!) and I think a really interesting look at the life of a person who goes against our stereotypes of what people in the past were "supposed" to be like.

note for writers: these are dated to the first time they were recorded, not necessarily to their first use. I imagine for many of these, they came about naturally through spoken language before they were written down anywhere. This is especially true of more underground slang because it's probably being recorded (in ways we still have) the least. So if you wanna use a term but it's a little off date-wise, give yourself some wiggle room.

also gonna take this moment to highlight two more i found recently:

Best boy: a sweetheart, a boyfriend, a husband. (1893) [w the obvious equivalent term 'best girl']

Honeydripper or honeydrips: a sexual partner (1917)
