From The DYI Dictionary and Thesewerous:
“It is widely accepted that eclat is in the same classroom so to say as Eugene, There’s an ‘e’ on the front for no reason at all and may be depressed.
Eclat or clat is the one of the verb forms of clot. Clat, clot, clod, clog. There you go.”
In a sentence, Never drink anything you don’t pay for or your head will feel like you have an e clat on the brain.
BEST DEFINITION YET! clat is past tense of clot! A+++++
