ouatMerci

What the picture shows

Bold red text reading "Eh !" on the top line and "Merci" below it, rendered in a thick sans-serif font with a slight drop shadow against a white background. Chatters likely use it to give a sarcastic or exaggerated thank-you, often after someone says something obvious or unhelpful.

No measured meaning yet. Used 118 times in 1 channels this month; one is written once chat gives enough evidence.
