Northern Irish.
I didn't really think I had one though, but then in Turkey whenever I spoke to anyone there they were like saying typical 'Belfast Phrases' to me in a jokey way.
For example the Turkish people would be like:
'Dead on mate.' or 'Aye your ma' to me
And the other day in some waterpark I was arguing with some kid over a slide, and when I was walking away the girl that worked there was like 'Where you from?' and I go 'Belfast' and she was like 'Yeah thought so.'
So I guess I do have a strong accent.
When I was younger though like around 2006-2008 I spoke with a heavy American accent for some reason, everyone passed comment on that and there's a video of me on my 10th Birthday and I could hear a yank accent
