A player of MMORPG's, such as World of Warcraft, that is only concerned with being on the top of the Damage Meter. They do not care for the group and are all about the DPS.
(player)"Yo let me see that damage meter 'cause you know I be dropping some mad DPS!" (Group): "Man this mofo is a chart topper."

When young adults or teenagers dress trendy and act like they are really cool. Often travel in packs with other chart toppers. They will often mimick clothing that they see on MTV. You may see them shopping at Hot Topic and Abercrombie & Fitch
