An incorrect usage of the babe meme.
Babe is something the chat would put on the end of their messages in an attempt to seem like Becky to troll Fraser during the Skyrim Lonesome streams while Becky was in the chatroom. People also went on to change their colors to the same as Becky's and put this at all the ends of their messages. Becky countered this move by changing her color to resemble MrChrisMad and putting Boss at the end of her messages.
Perhaps ironically, Babe is also one of Fraser's favorite movies, following Iron Giant.
