Derived from the word shack and flashback, a shackback is the act of reminiscing about shacks from weekends past. Shackbacks are usually shared with the two individuals who shacked together. See shack. Because shacking occurs commonly when both parties are intoxicated, conversations or actions that took place during and before the shack are easily lost in the fog of drunken memory, and thus, (attempting) to recall events from a particular shack can be quite humorous, if not slightly embarrassing.
G1: Last weekend's shack with you was spectacular!

G2: Indeed! I could say the same for you darling! I don't recall all too much from that night because I was totally smashed. But I remember dropping you into a bike rack while carrying you out to the taxi before we got back to the house!

G1: So that's why I have such an unsightly bruise on my hip! Ha ha ha! Oh, shackbacks!

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.
