Over Insein prison, planes spotted these messages by UK POWs ready for liberation: "Japs gone. Extract digit."
A person who carries out idiotic action even when they should know better.
For example, Donald Trump wiping his lips then shaking hands during a corona virus press conference.
Donald Trump is a known idiot when it comes to the corona virus.
When the words someone is saying descend into less and less useful details to the point that they realise they are not saying anything useful
I'm going to stop by the store to pickup some potatoes on my way home....hmm, should I get some green veg? I know we've got those leeks that needing up, but I was thinking it might be nice to do a roast on Sunday, and I don't want to have to go to the store again....ah, ignore me, I'm just wibbling here.
