It's something that people on the web (usually with a big mouth and a fake attitude) do when they want to look smart.
When something is said in a different language, they translate it with Altavista Babelfish and pretend to be smart and come with the translation like... Five minutes later.
<5 minutes later>
Annoying and pretend to be smart person (pretended to be away that five minutes): My mother is no whore! Yours is!
Pissed off person: You STUPID n00b you're just Babelfishing!!
