gibberish

Traders and brokerage firms have always used jargon and slang that sound like gibberish to the uninitiated.

Mr Gannon's mother Anne had dialled 999 after midnight and reported that her son was having breathing issues, "could barely get words out" and was speaking "gibberish".

As for the rest of it, even members of his staff couldn’t explain that gibberish.

Lots of praying and Bible verses and Jesus talk, which is gibberish to me, but means a lot to many good liberal Christians I know, so I'm not going to discount it out of hand.

Later that evening, Mr Williams began to "talk gibberish", pass out and wake up shouting "help me".
