The Vietnamese word "gắt gỏng" is an adjective used to describe someone who is churlish, grouchy, or bad-tempered. It’s often used to refer to a person who is easily irritated or quick to express annoyance.

(She is really grouchy today.)
Đừng có gắt gỏng với trẻ con.
(Don’t be bad-tempered with the kids.)
While "gắt gỏng" primarily refers to being grouchy or bad-tempered, it can also imply that someone is being overly critical or harsh in their judgments.
