NFL is an acronym used as a verb in informal contexts, often meaning to criticize or dismiss something in a blunt, league-wide sense, or more rarely, to crave or engage with American football culture as if ‘to NFL’ were a verb. In expert circles, this usage is highly niche and nonstandard; common practice favors noun/abbr. usage. Context usually makes the intended meaning clear, but usage as a verb remains uncommon and regionally variable.
