Ahlan dpatrick = welcome
Mudjer = Momel = boring
Mutheer = exciting but it is rearly used alone coz it means Hot (e.g. howa mutheer = he is hot, heya mutheera = she is hot = s exy)
but also we can say (hazehe al sayara mutheera lel entebah = this car is exciting for attention)
so the opposite of Mudjer which is commonly used is
Mosally = entertaining
