When a girl spends all day in her yoga pants because her arse is absolutely banging. She does loads of exercise and works up a right sweat then she whips her pants off and flicks them in your face so you get a good whiff before she lays her ham sandwich on you.
"My gf gave me a Dirty Neisha last night. I've washed my face 5 times and I can still smell it in my beard."
