five-by-five 

Originally an aeronautical term that is the equivalent to the modern "Loud & Clear". In slang usage, it means "great, fine"; popular in New England, it was made famous in "Buffy: the Vampire Slayer" from its overuse by the rogue slayer Faith.

"No worries, B. That vamp tried to kill us but I got mad skills. We're five-by-five here."
