A large gathering of seemingly popular girls forming an incredibly slow line or clump typically across a hallway, sidewalk, or basically any where in front of where you need to go. The bitch train seems not to realize your presence, and when an opening occurs it is almost immediately filled up again. Vaulting or Parkour might be required to get past the bitch train.
