fux0r

Fux0r is a leet (l33tspeak) variant of 'fuck,' swapping letters for numerals in the classic hacker/internet subculture style. It's an artifact of early internet and gaming culture from the late 1990s and 2000s, where replacing letters with visually similar numbers was both a style choice and a way to dodge content filters. Used in all the same ways as the original — as an expletive, a verb meaning to mess up or break something, or general internet trash-talk. Mostly nostalgic now, but still pops up in retro gaming and chan culture.

(internet slang, leet) fuck (in various senses).
