Verb. From Dutch.
“To sit around, relax and chat in-between courses of a meal”
This word has a literal meaning around the idea of stomach expansion or growth, yet it’s derived meaning is something more akin to what is common practise in mainland Europe: taking your time over food to appreciate the food and your company… a thing all too often forgotten about here in the UK.
Dutch is ridiculously hard to pronounce; uitbuiken sounds something like ‘ousbougen’ where the ‘g’ is pronounced at the back of the throat (…I know, right?!). The Germans have the word ‘ausbauchen’ meaning something similar derived from the Dutch version; that could also help with the pronunciation if you’re having difficulty!
