Thrall is the leader of the orcs that resides in orgrimmar
World of Warcraft is an online multi-player role playing game by Blizzard Entertainment. Thrall is one of the main characters and is the war chief of the Orcish Horde.
In Cataclysm, all over the leaders die, Alliance and Horde except for Org's leader which is Thrall.
Currently (in Wrath of the Lich King), it is Thrall. When Cataclysm hits the stores, Garosh Hellscream will become the leader of the Horde.

'Loptar' is not a word in the Warcraft franchise. A similar one I believe you are trying to ask about is pronounced 'Lok'tar', which is Orcish for 'Victory'. The entire phrase is considered to be 'Lok'tar ogar' meaning 'Victory or Death'. Though, in the MMORPG World of Warcraft, if you click on Thrall, he can be found saying "Lok'tar friend, what is it you wish?"
