Apparently it's most likely tied to the German municipality of Waake or the Swedish tribe of Vagoths. However most Lithuanians would likely explain it in the form of a joke - either about Germans being thieves ('vogti' = to steal) in reference to Teutonic/Livonic ordins, or about them being 'tough' or well armored ('vo kiets' ~= 'wow, tough/hard').
