What does that mean ?
Awhile back a poster, forget who, posted a news article "Beiber Stunned" over something or other, but they mistyped it "beeber stuned." Some posters will say things like "set your beeber to stune etc...
It became a running joke like "a moose bit my sister" or "this is hugh and series." (instead of huge and serious)
You’ve been here long enough to know when a bieber was stuned.
