"Dude, where is possibly the front of this bag?"
You have got to be kidding.
"Dude, where is possibly the front of this bag?" is a sentence that has never before been uttered by a single native English speaker.
"the front of this bag" should be translated "die Vorderseite dieser Tasche". The sentence in german should be written: "Mann, wo ist denn wohl die Vorderseite dieser Tasche?"
