A flock of young women from 'op North' who have migrated south, often for educational purposes and can often be observed squawking around bars in the middle of winter wearing little or no observable clothing.
I'm glad I wore my hat, coat and scarf tonight - it must be minus 5 out. Have you seen the flock of migratory birds flapping around the Oracle riverside? I don't know how they survive!
