[Japanese > English] What does "カンターレ" mean in this sentence?

I'm playing a game originally in Japanese and when a character did something unthinkably stupid, another character screamed at him "馬鹿カンターレ" or maybe "馬鹿カンターレー". What did she mean by that? There's not much context going on outside of that, there's nothing preceding it (technically, the full sentence is "もう、シロウのお馬鹿カンターレーーーーーー！" - シロウ is the name of the stupid guy), and later sentences are just ones berating that guy without anything noteworthy.
