In french: au jour d'aujourd'hui
Which kind of means "on today's day"... It really creeps me up!
In german: the words "voll" and "krass" which mean nothing and should be forbidden for any person with a brain and capable of formulating a sentence.
In english (or ratner american): how are you?/how do you do?
Placed at the begin of every meeting/call/discussion with my US collegues even if they do not even want to hear an answer.
