I was playing an online game and I noticed a player on my team with username "4PP13". I asked him what should I call him. He said "apple".

I didn't have second thoughts until I Googled it. It turned out "4PP13" does means apple according to Free Dictionary.

So what's the deal? Is this a special case? If not, what is this called?

    It's called "leetspeak" (variously 733tsp34k etc), where "leet" is a foreshortening of "elite", as these kids have been styling themselves since at least the mid-90s (which is when I, personally, first encountered it).

    It's like teenage slang; if you get it, you're in the gang. If you don't, you're a loser. No big deal unless you wanna hang with somebody that's 2 1337 2 CU Jun 19, 2015 at 15:47

    It should probably be explicitly noted somewhere that leetspeak is generally considered to be fairly obnoxious, and, as such, is almost always used ironically these days. Consider your friend apple an internet-hipster, if you will.

This is an example of Leetspeak, a relatively common internet pseudo-language/alphabet from a few years ago.

Leet (or "1337"), also known as eleet or leetspeak, is an alternative alphabet for the English language that is used primarily on the Internet. It uses various combinations of ASCII characters to replace Latinate letters. For example, leet spellings of the word leet include 1337 and l33t; eleet may be spelled 31337 or 3l33t.


  • Leetspeak originated in English-language texts, but its approach to orthography has also imported to other languages. In other Latin-alphabet texts that substitutions are often the same. I've also seen the same principles adapted to express Cyrillic in software systems that are Latin-only, such as text chat in Quake and Quake World.
