I do this too!
Or, er, I would, if I ever actually talked about the cereal anymore. But honest, I’d say it like that if it ever came up!
I use “li-berry”, “foilage”, and “nucular”, but mostly to irritate my friends. (I am SUCH a great person! :o )
But here’s a few:
Nazi --> pronounced like “snazzy”
and these I understand are a matter of accent, but since I’m not from the places that pronounce them this way, I would call it intentional mispronunciation on my part:
Tomorrow --> to-more-oh
Creek --> crick
Schedule --> shed-ule (in honor of my 10th grade english teacher)
Nerrer-cecily for necessarily.
