Can be used in numerous ways often with hilarious consequences when situated near a buffet...
"X has got a cheesy quiche" (Often sung)
"Oh, crusty quiche"
"Look at that fork-in quiche" (See what we did there)
Similar to other forms of sports widow (ie football widow, golf widow, etc)
This form of widowing involves being invited to the pub only to sit and watch ones partner play darts.
If one wishes they could embrace the darts widow mentality and become a darts wife, wearing large gold jewellery and garish colours. Tres chic...
"What you doing tonight? Do you want to come and be a darts widow?"
