This is the ultimate scientific mic drop! The dad claims -459.67°F is the coldest possible temperature, which is technically correct—that's absolute zero in Fahrenheit. But any physics nerd knows we typically express absolute zero as 0 Kelvin. The kid's "OK, Boomer" response isn't just generational sass—it's scientifically accurate shade! They're essentially saying "your units are outdated, old man." It's temperature trash talk at its finest, combining physics knowledge with perfect generational warfare.
