b00sted 4fun| 4 the Fun of Getting b00sted???

When the term b00sted 4fun appeared 40th on Google Trends, I can't help but ask Google what do b00sted 4fun meant. Of course, it is read as boosted for fun, but it seems like it is a company or something like that. Searches also reflect that it is a Russian Repository. Now, what on earth is a repository?

I checked if there's a site called b00sted4fun.com and it does exist, but containing only a page full of advertisements.

Another question related to this word is "b00sted 4fun Russian repo was hosted by what company?" An answer from answers.yahoo.com said "Dreamhost", so I guess they were really talking about websites.
