Pedobear is an internet meme which became popular through the imageboard 4chan. As its name suggests ("pedo" being short for pedophile), it is portrayed as a pedophile bear. The image was incorrectly described as a mascot among pedophiles, and cosplay participants dressed as the character were accused of being pedophiles, after the San Luis Obispo County Sheriff's Department issued a warning that Pedobear was a sign of the presence of pedophiles and other people with inappropriate sexual behavior.
Pedophilia or paedophilia is a psychiatric disorder in adults or late adolescents (persons age 16 and older) characterized by a primary or exclusive sexual interest in prepubescent children (generally age 13 years or younger, though onset of puberty may vary). The child must be at least five years younger in the case of adolescent pedophiles.According to the Diagnostic and Statistical Manual of Mental Disorders (DSM), pedophilia is a paraphilia in which a person has intense and recurrent sexual urges towards and fantasies about prepubescent children and on which feelings they have either acted or which cause distress or interpersonal difficulty.Source: Wikipedia
