The exact origin of this clip is undocumented, but it circulates widely on German-language meme soundboards and as a shared WhatsApp audio, where "smuus" became a stylised in-joke spelling of the English word "smooth". Like many sarcastic reaction clips passed around in group chats, it spread because the phrase fits almost any clumsy moment, and it now sits comfortably alongside classic meme soundboards staples that creators reach for when irony does the heavy lifting.
关于此声音
A short German meme voice clip saying 'Der war smuus' ('that was smooth'), played as a sarcastic reaction to clumsy fails, awkward slips and un-smooth moments.
This clip is a short German voice line saying "Der war smuus", a slangy stylised spelling of "that was smooth", delivered with a flat, deadpan tone that drips with irony. It runs about six and a half seconds, just long enough for the sarcasm to land after a spectacular fail. Creators drop it the instant someone faceplants, fumbles an easy play or pulls off something painfully un-smooth, and the gap between the praise and the disaster is what makes viewers laugh every time.
