Leet (1337) speak for 'hacker' — a classic piece of early internet geek culture where letters are swapped for numbers and symbols. H4x0r is used mostly ironically today, either to mock someone who thinks they're a big-deal hacker for figuring out basic stuff, or as a nostalgic nod to early 2000s internet forums and online gaming culture. Nobody who actually hacks uses it unironically, which is exactly the joke.

Oh wow, you figured out how to clear the browser cache — total h4x0r move there, respect.
Origin: From leet (1337) speak, an internet text style originating in early 1980s–90s hacker and gaming communities that substitutes letters with visually similar numbers: H=H, 4=A, x=x, 0=O, r=r. Editorial expansion authored on Slangora.
