Ahegao refers to an exaggerated facial expression popularised in Japanese anime and manga culture, typically showing rolled eyes and an open mouth. The expression moved from niche fan art into mainstream meme use during the 2010s, appearing on clothing, stickers and reaction images shared across social media. Short vocal clips named after it, much like anime ahh sounds, turn the visual gag into an audio cue. This version, shared under the Portuguese name ahegao do preglixo, circulates on soundboards where users collect brief anime reaction sounds for edits, streams and group chats.
