Presumably a very weird sex act. If it isn't, I'm sure that there all plenty of deviants prowling about there that will invent whatever the posh wellie is. I feel like it will have something to do with feet, seeing as a posh wellie is a nickname of sorts for Wellington Boots (I think) so it would make quite a bit of sense. It would also make sense for it to include rubbers, since Wellingtons are rubber boots. That's all I can think of, get to you glorious internet deviants.

A fud that is really in need of a good clean. Like it's been out all night on a fisherman's foot as he's been trawling the seas.

Calf or Knee Lenght stilletoe heeled boots, usually black leather or a cheap white PVC among knackers. Irish slang for "Fuck Me Boots'

Shut up! I love my superstars, call them that once again and I’ll bang you

'Spatula was powerless to resist. His eyes burnt into hers like mamellated chalcedony. His muscular arms enfolded her body as she felt herself being swept away on a noctilucent cloud of passion. "Am I the first?" whispered Dartanyan. "Sort of," she vouchsafed in return, her voice quivering with unrequited passion. "I've not let the other two have a shot on me melted welly yet."'

Comes from the word "incel". Celly welly is a gender neutral term for someone who is both an incel and a femcel. a total loner loser.
