I went to the beach with my friend yesterday. As we walked back we got into a strange lighthearted debate about the pronunciation of certain words. He has a weird thing that really annoys him about Americanisms coming over to the UK. We're both British and grew up in the same SE town, so roughly have the same accent.
He insisted that 'patriotic' is 'correctly' pronounced 'pat-riotic' not 'pay-triotic' like I would naturally say. See also all other versions of the word, patriot, patriotism etc.
When I tried to argue it's acceptable both ways, he insisted no, 'pay' is an Americanism.
He had a bunch of other words as well, including Lieutenant and Jaegermeister, but I can let those go. I'm sure I'm right with this one! 
Mumsnet can be extra cantankerous on Monday mornings so I'm just gonna clarify again, this was all lighthearted, and yes, there's bigger problems in the world, and no, this doesn't really warrant a thread but it's annoying me - so how do you say patriot?
