I got dis.
Frank's dad came over here from Cuba, and barely spoke any English. Frank was raised here in America. In school, teachers would read his name, and pronounce it 'Murr'. So he pronounced it that way as a kid, growing up.
A lot of Cuban families that moved to the US are/were cut off from their roots growing up, because of all the crazy shit that was going on forever between the US and Cuba, Fidel Castro, etc. there is little connection to their roots, and larger family history. So basically Frank had one person, his dad, saying it 'Meer', and everyone else (Americans) saying it a different way (Murr).
When Frank got into the UFC, and made that video as a 22 year old, his dad saw it and said you know, now is a good opportunity to correct it, and set the record straight. Because 'Meer' is the proper pronunciation. Frank thought you know what, you're right. From then on: Meer. Until Bork Lazer called him Murr again.
