British mum reacts to what Americans do

7. Something Americans don't do that you can hear from the young man in the baseball cap...

...in the longer video - a pronunciation oddity known as th fronting.

I recently learned about this phenomenon- substituting "f" for 'th" at the beginning of a word. Examples - "fink" instead of think and "fing" instead of thing. Also common is substituting "v" for "th" in the middle of a word - favver instead of father and "wevver" instead of weather, and so forth.

It's subtle, but once you know to listen for it, quite common. We watch a lot of English Premier League soccer at our house, and hear this all the time when British players are interviewed after a game.

Of interest in the longer video is the son does this, but his mother does not.
