"Beye3a" (Baye3a / Bayi3a / Baye3a / Beyi3a): Lebanese Slang, literally means "he has sold it" and metaphorically used to refer to someone who is careless, irresponsible and / or negligent (see "Msayyaf").
Sample conversation:
Person 1: "dude he has not renewed his driving license in years"
"3a Add Frashak Medd Ejreek / عقد فراشك مد اجريك" - Palestinian (or perhaps Greater Syria: Bilad al-Sham) Slang, literally means "stretch your legs as far as the mattress can take", metaphorically means "live within your means". Great slang for the current Economic Crisis that we live in...
