What does mouthy mean?
Mouthy is an informal adjective for someone who talks excessively, especially when their talk becomes argumentative, complaining, or disruptive. It is often more disapproving than simply talkative: calling a person mouthy usually suggests that they are saying too much or making a fuss rather than merely being sociable. The word is used in both British and American English, though British usage can place greater emphasis on quarrelsomeness and fussiness. It is especially natural when describing children, teenagers, or people who react noisily to criticism, but it can apply to anyone who dominates a conversation. Mouthy should generally be avoided in formal reports or polite descriptions because of its critical tone. The related verb mouth, meaning to speak or move the lips in a way that distorts the words, is also informal and is sometimes used critically, as in the expression "don't mouth off."
