This is a very apt title to an article. True.

Literally some times a match goes on for so long, the players get so hot, so exhausted, so frustrated, play erratically and inconsistently, up and down like a yo yo and cannot settle down, get agitated with the slightest thing, eg dicy referee call, and bingo out comes a mouthful of stuff, often referred to as verbal diarrhoea, or brain explosion..

That is bad enough in itself, causing a scene, acting in a non professional manner, reliving the incident during a postmortem, and making the necessary amends.  Not a good look.
