Mellstroy, real name Andrey Burim, is a Belarusian born Russian speaking streamer who built a huge online following with loud, unpredictable live broadcasts and viral clips shared across TikTok, YouTube Shorts and Telegram. Short out of context phrases from his streams are often clipped and reused as soundboard memes, and arbuz follows that pattern. The Russian word for watermelon became a standalone joke among fans, quoted and dropped into unrelated videos for its randomness. It remains popular because his delivery makes even a single everyday word instantly recognisable.
