Pan Am used the term "Killer items" for their 'takeoff configuration check'.
I use FET, misspelled FAT, as in "I'm in fat city", which is U.S. slang for being in great shape.
F - Flaps
E - Engines
T - Trim
"Taxi into position and hold." Runway's clear, no one on final approach, FO calls out last minute checklist items...silently check FET(flaps, engines, trim). Good to go.
