A long thin pill that is used for antianxiety treatment, and/or for people with bad nerve problems. It has four sections, and is basically just four xanax per pill or "bar".

Most people take half to four of these at a time with alcohol. It tremendously increases the effects of alcohol, and most people have a huge amount of memory loss the next after taking it. They are not able to remember much of what happened or what they did the night before.

a benzodiazapine used for anxiety and insomnia. one xanax relaxes your muscles and makes you feel tipsy. xanbar is the equivalent of FOUR XANAX. usually accompanied by alcohol which makes for a nice clean DRUNK, but usually results in extreme memory loss and negative recollection of the prior day's events.
If it weren't for the ridiculously strong effects of xanbar, I would've never drunkenly hooked up with that guy at Carina's surprise birthday party a year ago.
That guy is now my lovely boyfriend.
