This Forum is mercifully free of Jargon. LOL, along with, IMO in my opinion, and possibly WFP are some of the few example i can think of.
Remember when CB radio was all the rage, whats your twenty? Handle- name. They had a word for everything except the proper one. What a lot of plonkers!
When car boots hadn't been going long Sun published a list of words so you could be in the booters clique. Members of the public or punters were called civilians!
So, we haven't got a lot of words that are just peculiar to us and that's a good thing LOL
