None of many official and authoritative dictionaries I checked online describe "burnout" as does this Wikipedia article. What I'm talking about is this:
I checked:
Cambridge Dictionary
American Heritage Dictionary
Random House Kernerman Webster's Dictionary
Oxford Dictionaries (at lexico.com)
Merriam-Webster Dictionary
Collins English Dictionary

The only place I've seen this definition is in Wiktionary where it is the last and fifth definition given, after definitions 2 and 3, which would seem to suggest these meanings are more frequently encountered:
- (US, slang) A marijuana addict; one whose brains have been burned out.
- (aeronautics, space) The shutoff of a rocket motor following the complete exhaustion of its fuel supply, or having been irreversibly throttled after the application of a planned delta-v.
The Wikipedia article says that a "burnout" can also be called a "peelout" or "power brake", but from what I've seen "burnout" seems to be much commoner than either of those two alternatives. "Peelout" or "peel-out" and "power brake", if found in dictionaries at all, often have inconsistent meanings among each other. One I saw gave the definition of "peelout" as what I would call a skid (as in coming to a stop with the wheels stationary). Wiktionary doesn't list this "peelout" as a "burnout", other dictionaries list "peel out" as a phrasal verb meaning to depart quickly and noisily in a car or motorcycle, and "power brake" gives results like this:
A motor vehicle brake assisted by a power mechanism operated by the engine that amplifies pressure applied to the brake pedal.

What I find surprising is that to my knowledge "burnout" isn't really slang or informal. The Wiktionary entry listed definition 2, a marijuana addict, as US slang, but didn't mark spinning tires meaning at all. If I were giving testimony in a court I would most likely use this word instead of saying "He spun his wheels and blew up smoke from his tires."
Is "burnout" not the overwhelmingly commonest word for this action? Is it slang or informal? And if it isn't, why isn't this meaning defined in dictionaries? Even informal and slang terms are defined in official dictionaries, and I thought "burnout" was a very common term. It's something I thought all of us see and hear all the time. And I'd bet some of us do little mini versions of this when we take off too fast, especially in front-wheel drive cars.
