Kind of like a spoonerism, which I also do embarrassingly often, but with whole words? For example I just got of the phone with my mom by telling her I needed to run to the store for toothpaper and toilet paste.
I don’t know, but you made me laugh.
It’s called a manwolfism, isn’t it?
Would that be a form of dyslexia?
Nope. it’s called “lysdexia.” 
Bravo. Well played, Good Sir.
I had a similar thought yesterday but didn’t post. Yours is better than mine would have been.
It’s still a form of spoonerism, I think. Itself a subset of metathesis.
