A Bieber Dam is when a large horde of Justin Bieber fans block entrys, doors, halls, roads etc. similiar to a beaver dam.
John: Hey I think Justin Bieber's signing autographs in the mall food court today
Sam: Ya he is, did you see the size of that Bieber dam? no one can get through to the other side of the mall.

The equivalent of a Rick Roll on YouTube, but with a Justin Bieber video, instead of Rick Astley.
Can also happen on torrent when you think you are downloading a James Bond movie called "Never Say Never" and then find out it's a Justin Bieber movie.
