About this sound
This short voice clip features a woman delivering the Portuguese line attributed to Ruca's mother, urging him to go wash his backside, in about three seconds. It feels cheeky, scolding and deliberately rude, like a mother losing patience in the funniest way. The uploader notes it was taken from the Kesyn & Skelter channel.
