A Bar Star is someone who frequently takes the prescription drug called
Xanax. This provides a feeling of extreme relaxation and you do not remember most of the things you do.
People frequently take
Xanax before drinking because it increases the effects of alcohol.
"Hey
Will, wanna cop some bars for this week so we can blackout every day?"
"Louis, you've taken 4 bars everyday for the past 4 months... You'
re such a bar star."
"Lets put bars in the bottles at the club tonight so all the
girls blackout and we can rape them!"
