like a shag on a rock

like a shag on a rock

Isolated, lonely, stranded, or abandoned. (A shag is an Australian term for a cormorant, which often perches alone on cliffsides.) Primarily heard in Australia. I can't believe you just got up and left me there like a shag on a rock! Even at parties around lots of people, I still tend to feel like a shag on a rock.
