New slang will evolve eventually. Me, I just call them Euros (en masse) and get depressed over the exchange rate.

My fave slang for US currency has always been dead presidents

Primal - the BBC TV programme Click covered Cuil last night, and didn’t trouble its English-speaking viewership with how ridiculous the “Irish” name is, instead in the brief and dismissmive report just told how the new search engine says its name should be pronounced.

If I ever become social again I’ll keep a close eye on regional variations.

Cuid (quid for English speakers - don’t want to have Cuil being pronounced quil now do we?) I’ve found to be used for notes only.

Now that I remember, a two pound piece may be used for the €2.

All that said, I am a KE-reg, you a D. There will be differences/variations. What we need here is input from the G, C, DL etc. regs.

Primal - That carpenter friend of yours wouldn’t have that issue if he wore an itsy bitsy teeny weeny yellow polka dot bikini.

I hadn’t discerned yo-yos being exclusively a coin term - is it? And I can’t say for certain but I would have guessed that I’ve heard cuid used for all forms. I need to pay more attention. Or just start my own terms. There could be gold in it. Nordic gold.

Rubbish and junk are commonly used for 1c and 2c. The 5c could be included in this were it not for the pint in so many places costing €x.x5 - it is therefore a useful denomination.

Shrapnel for all coins below €1 though the word was in use pre-euro.

The €1 and €2 may be heard referred to as 1 yo-yo and 2 yo-yos or simply as a 1 and a 2 sans euro.

I’ve heard quid used for notes but not coin. Never have a heard a term that specifically applies to the 10c-20c-50c grouping.

Now none of that was of any help to you I know, but just to help you even less I’ll tell you a carpenter friend of mine always says the clankle-clankle during the week leads to the crinkle-crinkle on a Friday which becomes the clinkle-clinkle by Monday.
