Eastern Sydney racial slang for middle eastern ethnic groups. As a reaction to the Cronulla crisis of 2005, white Australians came up with the term to describe the ugly headress wearing muslims and screwed in the head Lebs.
"Shit man, did you see that sippo?"
"Yeah, let's go bash her ugly face back to Muslimia"
"Dude, Muslimia isnt a place"
"Ahah, that's a good insult. Yeah youre right, Muslimia isn't a place, it's a shit hole."
