Hi Tasya In English, if you 'put your foot in your mouth' you are saying something inappropriate or embarrassing - it's making yourself look like an idiot. So, if someone suffers from "foot-in-mouth afflictions" it means they keep saying stupid or embarrassing things and then wishing that you hadn't.

Well to answer your question I have a question to ask of you. Was it the title of a story or was it part of a report? There is a disease called foot and mouth. Foot and mouth afflictions is saying about those who have foot and mouth disease
