An exclamation used to express happiness and/or satisfaction after completing a task or under the influence of drugs. It is often preceded with a phrase of little to no meaning.
The expression can also be used spontaneously in moments of excitement and happiness.
The origin of the expression goes back to 2017 when it was first used by DJ "Szmitek" in one of his mixes published on YouTube.
The sound of a toy, which when turned on one end, makes a distinct 'groan' sound. This is due to a noise maker in the tube, that when it falls, vibrates in the air making the noise. The groan tube was invented in the early 1960s by Japanese toy manufacturer Kureo. The toy was first sold as 'Magic Noise Tube"
Hey bro do you know where the sound “Uuuua Auuuu” comes from?
