The hip way to tell someone to get lost. Comes from the movie Friday. Great movie.
The main character Ice Cube says it whenever Felicia--a minor character whom he dislikes-- is finally getting

The thing is, only people who were maybe two years old when Friday came out use the term today and, perhaps not coincidentally, they are Hufflepuffs. They also use terms like Gucci and speak in hushed tones about Beyoncé's enlarged, pregnant uterus.
