When a line or group of basic bitches walk past or near your direction. Basic trains are popular among high school hallways . Multiple basic bitches give rude looks while passing by to make themselves feel intimidating.
Person A- "Did you see those basic bitches passing by?"

Person B- "Yea, it was a basic train!"
