suckin diesel 

From a Northern Irelander:

"Suckin Diesel" should only be used to describe a situation which has recently improved.

The situation should have been so bad that little or no progress had been made for some time. It should only be said after an event or action which allows further progress to be made.
John: What are you doing Dave?
Dave: Trying to get my computer to work.
John: Been at it long?
Dave: yeah about 3 hours mate, I can't seem to get it switched on. Any ideas?
John: Have you tried plugging it in and flicking the switch on the wall??

(Dave plugs PC in and flicks switch. PC starts to boot up.)

Dave: "Ahhh...now we're Suckin Diesel!!"

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.
