In Scotland, it is used to describe a girl who is really fucking ugly. Used in the same conitation as the word munter. To be munterlicious is to be uglier than someone who is a munter
"Check her out, shes munterlicious!" "gads min, state of her munterlicious face!" " no wonder your shagging him, his girlfriend is munterlicious!!"
