The word itself wasn't new: People had been "goons" as a synonym for "idiots" for decades, but Segar's character gave it a second, more sinister meaning. Since Alice the Goon was essentially a hired thug, by 1938, the word was being used in reference to hoodlums hired to break up unions, and that usage persisted -- to the point where today, when someone mentions a "goon squad," it's a cinch that they're talking about crooks, rather than morons.

The alternative "procurer of male prostitutes for sea witches" meaning never caught on.
But there's more. Three years after Alice first showed up, Segar introduced another bizarre character destined to expand the English language: Eugene the Jeep, a small critter that looks like an awkward-to-produce cross between a giraffe and a dog who can do things like teleport, walk through walls, climb on ceilings, and basically just tell the laws of physics to go fuck themselves.
