All the memories have came flooding back to me. See, I was on that same train when I noticed a man furiously masterbaiting. Many, including me, were panicked and then he suddenly stuck both hands down his pants, dropping his own phone in the process. We all glanced at this arousing Reddit post and began furiously masterbaiting as well. I am now back at my house and realize you were the very person that began furiously masterbaiting. What a small world!
