Words Inspired by Television
Solution 1:
One such is cowabunga, which appears in ODO.
exclamation, informal
used to express delight or satisfaction.1950s: first popularized by a character on the US television programme Howdy Doody (1947–60). It later became associated with surfing culture and was further popularized by use on the US television cartoon programme Teenage Mutant Ninja Turtles (1987–96)
Others include [courtesy of OED]...
- bippy Rowan & Martin's Laugh-In (US, 1968–72)
- craic SBB ina Shuí (Ireland, 1976–83)
- dibble Top Cat (US, 1960–61; UK from 1962)
- doomwatch Doomwatch (UK, 1970)
- jobsworth That's Life (UK, 1973–94)
- scooby [rhyming slang for clue] Scooby Doo (US/UK, 1960s)
- spam [as in all-smothering multiple copies] Monty Python's Flying Circus (UK, 1971)
- Tardis Doctor Who (UK, 1963–present)
Solution 2:
Seinfeld's classic yada yada made it into the OED in 2006.
From Merriam-Webster (since I don't have the OED with me now):
Yada yada: boring or empty talk. Often used interjectionally especially in recounting words regarded as too dull or predictable to be worth repeating. "listening to a lot of yada yada about the economy"
And on a different note, there's jumping the shark from Happy Days, although that's a bit of a meta-example.
Solution 3:
Your question is a bit confusing. You ask for words "inspired by a television show or movie" but the example you give (doh) was popularized by The Simpsons, not inspired by it. The OED's first citation for doh is:
1945 T. Kavanagh It's That Man Again (B.B.C. radio script) 8th Ser. No. 166, Tom: Yes, out of the nest–Diana: What nest? Tom: In those whiskers–Diana: Dooh! Its [sic] no good talking to you.
So perhaps you could clarify the question?
Anyway, here are a few examples of words inspired by movies, from the OED:
Rosebud, n. Something likened to the ‘Rosebud’ of Citizen Kane in being an enigmatic clue which provides revelatory insight into a person's character.
Star Wars n. the title of a popular science-fiction film released in 1977, used (chiefly attrib.) as the informal name for a military defence strategy proposed by U.S. President Reagan in 1983, in which enemy weapons would be destroyed in space by lasers, antiballistic missiles, etc., launched or directed from orbiting military satellites.
Strangelove, n. Used transf. to designate one who ruthlessly considers or plans nuclear warfare.
Solution 4:
Tardis
noun
1. a time machine.
2. a building or container that is larger inside than it appears to be from outside.Origin:
the name (said to be an acronym of time and relative dimensions in space) of a time machine which had the exterior of a police telephone box in the British TV science-fiction series Doctor Who, first broadcast in 1963.
