This is a whole new one!

Came across this just now on a MN thread..... "It's a proper two and throw conversation"

I've just seen that 😂😂

What is it meant to be?

To and fro I am assuming!

Oh I love it

I saw that and couldn't work out what it was meant to mean

I came to pedants corner in the hope someone had started a thread on this one!!

I thought, what have I just read?

Most incorrect sayings you can at least see the logic of how it's been misunderstood, but this one I'm at a loss with!

It's because a lot of people can't/don't pronounce "th".
