Big John built a large TikTok following with cheerful food videos, huge takeaway orders and the repeated catchphrase 'bosh' delivered at the start of a meal. Clips of the shout were cut into a standalone sound as fans began reusing it for their own orders and food reveals. The Chinese takeaway connection became central to the joke, with the line signalling an unusually large order is coming. It remains popular in short food edits because the meaning is clear even without seeing the original video.
