A millibitcoin: 1/1000 of a bitcoin, or .001 bitcoins. Used because the bitcoin, although highly fluctuating, has been very high: over a hundred dollars, and nobody wants to have to deal with all of the decimals in small transactions. Perhaps, if bitcoins take off, we will have to start using microbitcoins (µBTC).

Michaels Behind the Couch (MBTC) 

MBTC is an organized group of people. The sexiest, funniest, but also cutest of people on the earth. With prolly the biggest cocks in the whole universe. Michaels behind the couch is easily the coolest of n words. This brotherhood could never be broken and will be passed on until the end of time. The jokes never stop ending and just become funnier and funnier. The popularity of this group is insane but it keeps growing along with each of our pps. The humor in this group is just unreal. We believe the goal of this group is to become as cool as the one know as camilou and soon make history as the funniest people on the planet.
Bob- U know that amazing group chat

Joe-yes the one and only MIchaels Behind the Couch (MBTC)

trucker's tan 

A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
I had a trucker's tan after driving for 10 straight hours on a sunny day.

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.
