Hijazi/Saudi Arabic: مهبق

[fufuswaffles]

سالم، انت تعرف ان ايش ممكن اسوي فيك بالذات انك مهبّق من المدرسة.​

I assume from the context it means absent. Is that right? Are there other meanings? Does anyone know its origin? ه-ب-ق doesn't seem be an Arabic root​

 

[Wadi Hanifa]

My understanding is that in this context it means to go out on a frolic (and more generally to do something on a whim ليش سويت كذا؟ والله هبقة).
