I still remember "pwned" as a misspelling of "owned." Then of course there were all the other l33t spellings, but pwnd seemed to be the one most specifically about mistyping. Gen-Zers sometimes end statements with "Periodt." They also have lots of other phonetic ones, like "rizz," but that's more about the phonetics and less about the humor in misspelling.

I never connected that pwned was a mispelling of owned, I always thought it was a word of its own.

More of a typo than a spello in the sense that P is next to O on the qwerty keyboard so gets hit occasionally, especially in the tense rush of online gaming.

Similar to zomg, because z is next to the shift key and they were going for OMG.

And then there's this!1!!eleven

Apparently due to intermittent shifting of 1 into an exclamation point, occasionally yielding multiple 1s, which can look like a random eleven, which is humorous to skip to directly.
