What words or phrases did you make up that people have started using?

One i'm fairly sure I came up with by chance is quite offensive. I know this is AH but I don't want to piss off an entire demographic with five letters. It's not racist or homophobic though, yes I'm aware that I'm virtually doing that 'I've a secret but I can't tell' thing and am therefore a cúnt:o So allow me to make it up to you with another one, one that is now legendary in the area of its origins. This is the story of 'Good man lads'.

In my hometown which is in the countryside, a common form of greeting amongst familiars is 'Well', as in 'Well Bob, your name is a palindrome!' A similar unorthodox greeting albeit from man to man is 'Good man', whether he is a good man or not is completely irrelevant, as in 'Good man Clive, are you off the sex offenders register yet?'

So, one day in the distant-enough past, me and my friend Andy were in his sitting room watching a football match on tv. Amongst us elders were Andy's younger brother and his friends. I got a call from a mate, let's call him Steve, to see where we were, he was doing the rounds and was going to call up. Now Steve is a bit of a character in the area and beyond, and not by choice. I am full sure there will be a book about him and his -isms some day, he has touched many peoples' lives!

Anyway, up to the house he came. Football isn't his thing and besides that the room was a bit crowded and stuffy, so me and Andy said we'd go outside to meet him. But just as we were about to leave the room, there was a goal in the match. Between air-punching and watching the replay we forgot about Steve and into the room he came. Everyone looked in his direction, the young lads in the room knew him and all said 'Well Steve' and the like, he simply looked around a bit confused and said quite nobley 'Good man lads', I broke my shíte laughing, as did all in the room. When we left the young lads had tears rolling down their cheeks.

Me and Andy had to explain to him going up the road why everyone was laughing,which is part of the reason it is quite funny. The man doesn't set out to say these things and if he told a joke, it would not be funny and quite possibly mixed up with 5 other jokes. Within weeks I saw boyracers going around the town with a banner saying 'Good man lads' on the top of the windscreen where it would usually say 'no fear' or some other shíte. It has worked its way naturally into every day speech amongst at least 100 people. In fairness, it is quite a useful greeting. That's my way-too-long contribution.

TL:DR 'Good man lads' For those times when greeting everyone in a room individually is a) too much hassle and/or b) when you can't remember everyone's name.
