There’s no real known origin as far as I’m aware. There’s nothing called a Donk either, but the -en specifies that it’s the Donk we’re talking about and not “a Donk” (en Donk). Honestly it’s probably just something like “McDonalds>McDonken>Donken”. It’s shorter and gives it a personality.
It’s a pet name for McDonald’s. It didn’t have a meaning prior.
Do you know the origin? Maccas, mackies, mickyDs, McFat, you can make assumptions about how these came about. Is there an origin story for Donken?
