1337 flipped upside down spells leet, kind-of like the internet slang equivalent to 8008135. People put it as their clan tag in video games, or as their password on their PC's. No one really uses it anymore, it's more of a 2000s thing, so it's got a certain stigma behind it in that weird, in-joke kind of way. Also, there's lots of people using that as an excuse for otherwise lame screenshots. Better yet, just leave this number alone. It's already overused.
