chach/chachi 

A guy into the following: his fraternity, spring break, Dave Matthews, sports bars, chain restaurants, Abercrombie and Fitch, thinly-veiled misogyny. From the character "Chachi" of "Happy Days" and "Joanie Loves Chachi" fame. Oddly, Chachi himself did not fit the above criteria; yet, he embodied the essence of trying way too hard and having no fucking clue.
At my cousin's bachelorette party, we ended up at Senor Frog's - full of chaches. I had to bail.

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.
