The boom rating came from A.J. and Big Justice, the father and son Costco Guys who went viral on TikTok in 2024 rating food with booms instead of stars. Five booms became their highest praise, and other creators quickly copied the format for products, plays and personal news. The joke darkened into parody as users awarded five big booms to losses, accidents and lines like sorry your brother died, where the enthusiastic score clashes with the news. That mismatch keeps the clip useful as shorthand for ironic celebration online.
