An ex boyfriend who follows you at work asking why you are with your current boyfriend instead of him, and sends you an untold amount of messages on the internet asking you to come back to him, and spends the rest of his time sulking and crying to his other friends..... this is Emoberry
a disheartening seed planted verbally by one emo individual into a non-emo individual. side effects of an emoberry include a more pessimistic view point of a certain subject or just a more meloncholy mood overall.
