Literal Translation: "Whom would show the bear the path to their own vineyard"
This expression is used as a rhetorical question signifying that the subject "brought it upon himself". It is sometimes used to signify stupidity or simplicity (in its pejorative meaning) of said subject. As in: "Who would lead the enemy into their own territory?"

Sample conversation:

Person 1: "I cannot believe John is introducing oh-so-handsome Jude to his girlfriend! This guy is a Don Juan! No woman can resist him!"

Person 2: "I hear you man! 7ada Bi Jib El Debb La Karmo?"
