Dota Mode orginates from a popular online game called Defense of the Ancients created by a cool guy as a custom made for Warcraft III frozen throne. Dota Mode is when a person is in a state of nullness since he is 100% concentrated on this game that nothing can effect him or get his attention. The only way to break a "dota mode" is with a hot girl.
