My friend :hey Koussay kan you give me q cigarettes
Me : you can get l3asba
Here it means litterly :you can get my dick but the real meaning is :no i wont give you
Also it's used
like a swearing word (it's always a swear but here it can put u in trouble) my friend: 3asba lik
Me punchs him in the face because we tunisans get angry fast against swearing except if it's joking so here 3asba lik means
something like
fuck you but more hurtful and powerful
