The voice belongs to Jeffy, the puppet kid from Logan Thirtyacre's SML (SuperMarioLogan) YouTube series, whose slurred speech and tantrums made him one of the channel's most quotable characters. The exact episode this line comes from is not documented, but the clip took on a second life as a reaction sound on TikTok, YouTube Shorts and Discord soundboards, where it is dropped over anything deemed nasty or sus. It belongs to the same family of reaction sounds as the classic bruh clip, and like that meme it stays popular because one blunt line says what the comment section is thinking.

Jeffy's slurred voice saying 'that bih nasty' from the SML YouTube series. A reaction clip creators drop over gross, cringe or sus moments in memes and edits.
This is a short voice clip of Jeffy, the dim-witted puppet kid from the SML (SuperMarioLogan) YouTube comedy series, drawling the phrase 'that bih nasty' in his trademark slurred, nasally tone. The delivery is slow and judgmental, like a kid calling out something disgusting he just witnessed, and the raw, unfiltered bluntness is exactly what makes it funny. Dropped into an edit, it lands as an instant verdict on whatever is on screen, turning a gross fail, a sus comment or a cringe reveal into a punchline. Viewers who know Jeffy hear his chaotic energy immediately, which makes the roast hit even harder.
