originates from vietnamese slang- "Dou ma" means to "fuck your (respondent's) mum". However, the single word "dou", implicit of its infinitive form, "to dou"; means to "screw someone up", usually through physical means like bashing their face in or the application of an armbar or strangle. Its coinage is credited to an anonymous ABV and ABC known only (urban dic. rules) as "teabag" and FC.
