A chain (mainly used on instagram) started by one person. You repost the picture so people get to like the picture and you and the people who reposted the picture or didn't need to follow everyone who liked the picture. If anyone that you followed that liked the picture does not follow back within 24 hours, you unfollow them. Followtrains help you gain a whole bunch of followers without apps or pay.
Person: How did you get so many followers? You probably buy your followers.
Me: Followtrains, bitch.
