Shiffing is a Fantasy Football term for ripping off your friends by trading several inferior players for fewer high quality players. this includes harrassment through posting comments and text messages, and dealing this with people who obviously have no clue what they are doing. Then talking smack and being a jerk after the trade by verbally berating and being a bitch about it to the person he ripped off. It also includes the OCD technique of bombarding everyone with random horrible trade offers
Man, all that Shiffing before that trade must have made you crazy!, and he's been Shiffing me too, but I cant stand dealing with all that crap. Its ruined all the fun in our league!

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.
