Etymology
limophilia derives from the Latin word "limo" which means "slime" and the Greek word "philia" which means "love". It literally means 'love slime.'

Pygophilia 

Sexual arousal from seeing or touching the buttocks of another person. The term is not gender-specific. A person who is thus aroused is a "pygophilist" or "pygophile"; "pygophiliac" may be used if the arousal could be considered abnormal, pathological or extreme. In a finer sense, "pygophilist" can be used to infer a person whose predilection includes actively touching buttocks, as the suffix -ist connotes "one who does", whereas "phygophile" (-phile, "one who likes) could include those who are content merely to look at buttocks.
Pygophilia is not that uncommon - my best friend is a total pygophilist - but that guy at the office has had his hands on more ass than a donkey breeder; he's a complete pygophiliac.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
