Fire Truck Frame 

A split second frame of another scene at the end of a video, typically for comedic value. The name comes from the ending frame of the most popularized upload of "Steamed Hams" (Skinner invites Chalmers on steamed hams Uploaded by marre523 on Dec 2, 2010) which shows less than a second of a fire truck driving. The first use of this phrase can be attributed to a comment on the video "Is that a flute? (Tenacious D Fan Animation)" by Dongff·tk, which features a fire truck frame of Kyle Gass. The pinned comment, made by @thetwistedsamurai, read "The split second of Kyle smiling has SUCH 'firetruck frame from Steamed Hams' vibes." Garnering 5.3k likes as of recent.

"That fire truck frame caught me off guard, lmfao."
