Someone on Twitter, I'm pretty sure just a normal person, not a celebrity or news/entertainment journalist or whatever, pointed out that Lena Dunham is more famous for being a walking cringe factory than she is for being an actor or writer and it's probable that Odell Becham Jr simply had no idea who the fuck she was. It's one thing if Michelle Obama walks in a room and you ignore her, that's extraordinarily rude, but you can't expect someone to go out of their way and introduce themselves to every single person who walks through the door.
