Both left-handed; principal left, but makes use of right-hand for certain tasks. As opposed to thought so it implies bad with both of your hands, the term "bad" isn't inside. It derives from Latin. Ambi=Both and sinister=Left. The alternative of ambisinistrous is ambidextrous therefore both right-handed. It does not mean great with both hands. All left handed folks are obligated to be ambisinistrous because in the right passed world, there are lots of things that are not made for left-handed individuals. by QuinnReport definition
