look up any word, like bangarang:
 
1.
One who continually parties to all hours of the night only to sleep for 1-2 hours and get up and do it again. Keep in mind having no job or a part time job is a requirement for being a Dirty Stayout. Those who are deemed the title "Dirty Stayout" usually enjoy the title and should request a meeting at degenerates r' us.
Jasmine does not have a job. Jasmine goes out Monday til 5 am comes home sleeps til 4 pm. Gets up Tuesday, goes out til 7am, comes home sleeps til 2pm....and continue the pattern throught the entire work week and weekend.

Jasmine is a dirty stayout, she should stop.
