Variety slang
Variety has been using idiosyncratic and hyperbolic slang for about a hundred years now: ankle, biopic, boffo, chopsocky, helm, hoofer, nix, oater, percenter, scribbler, skein, sudser, terp, warble, whammo, yawner, etc.
It turns out that the official website now provides a glossary page explaining a lot of their terms.
Some of the terms listed are not specific to Variety, of course. But some words that have become common in everyday use—such as "sitcom"—were apparently coined by Variety.
