Fartlek by YourUrbanPerson March 4, 2022
From the German translation 'Speed Play', fartlek is a training exercise used by distance runners to increase their anaroebic capacity. This increases racing performance greatly by allowing muscles to better cope with the lack of oxygen associated with high-intensity activities. The process involves speeding up to race pace for several minutes, then jogging for several minutes, repeating until workout is over.

Fartneken 

The frankly disturbing act of inserting one end of a length of hosepipe up your anus, placing the other end into a drink, then expelling your fart through said pipe. The result is the formation of a methane infused beverage as the gas bubbles through the drink. The drink should then be enthusiastically guzzled by yourself / lover / friend / victim.

See also Stealth - Fartneken where you do this to an unbeknown recipient who will wonder why you are laughing as they down their 'fruity elixir'.

The discipline has also given rise to several sub genres according to odour, volume, bubble volume etc.
'A great meal rounded off superbly when Fatty had to see off 3 Fartnekens after losing at spoof. Turnip with a hint of peanut too. Result.'

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.
