I used to think it was spelled Pikatu, but pronounced with a chu because of the American accent. Like 'century'.
This was when Pokemon first came out. Everyone was talking about it, but I hadn't gotten the game yet.
Non-gaming one, I used to think Ke$ha was pronounced 'Keesha'. I found out about her music after I moved here to Jordan, so I never actually heard anyone say her name until like a year later on TV.
