About this sound
A short reaction clip of someone asking what do you mean by that. Used as a confused response sound effect in memes, edits and chats.
This is a brief vocal reaction lasting just under a second, with a questioning voice saying what do you mean by that. The tone is confused and slightly accusatory, delivered like a direct call-out in conversation. It lands as a quick pause in a video, making the moment feel caught out or needing explanation, and it works best when the timing is sharp right after a suspicious or unclear statement.
