Time magazine (September 30) carries the article titled “Christie to Watch Football” followed by the lead copy: “Garden Stater in no rush to decide, will mull while gridironing this weekend. AP finally weighs in: Christie "reconsidering" his decision not to run. ”
From the headline, it is easily to understood that ‘gridironing’ refers to watching football game. But as I checked both of Cambridge Dictionary and Merriam-Webster Dictionary and others on line, there was no mention of ‘gridiron’ as a verb.
Merriam Webster defines ‘gridiron’ as the noun meaning;
a gated iron utensil for broiling flesh and fish over coals.
An openwork frame on which vessels are placed for examination, cleaning, and repairs.
A football field.
Cambridge Dictionary defines it simply;
noun. a field painted with lines for American football.
I know people use nouns as verbs very often today. Even we Japanese say ‘I baseballed yesterday.’ ‘Let’s movie today,’ ‘I forgot to breakfast this morning,' by omitting do, take, play to shorten the sentence. But is it right to use ‘gridiron’ in the verb or gerund form which no dictionary (as far as I checked) provides as used in the Time article? Can we substitute most nouns (not saying every noun) for verb / gerund, like 'I'm philosophying today,''The doctor coughed while surgerying.'?
