A term used for someone who neglects children to play MMORPG. They tend to neglect their children, wife/husband and family members. Relationships with virtual partners normally form and are also found out. Normally families are broken apart, and the "Langelos" is made into a joke.
"You fucking Langelos, I hate you. "
"Dad when I grow up, I want to be 29 and neglect my children, just like you"
