hagged over

after a night of drinking, you wake up to find the girl you've been with all night lies next to you in bed, but instead of being the beauty you'd imagined her to be the in yester-night, she now turns out to be completely hagged over.

...and then she turns around and oh my god she's totally hagged over so I threw up and said that it's cause I'm totally hung over.

Dance hag

A woman who has a tireless appetite for dancing and is not only very good at it but is also much fun to be around.

Subject may also be described as being just like 'one of the boys'. A term of endearment.

Off to the pub later, I think Amy is going to tag along, she is a real dance hag.
