Dirty Sixth 

The historic entertainment strip of Sixth street in Austin, Texas, specifically East Sixth Street from Congress Avenue to highway 35. Dense with wild bars and dance clubs, there’s a reason it’s not referred to as Clean Sixth.

After happy hour let’s get weird on Dirty Sixth.

zero to sixty 

Usually when someone goes from being really calm or content, to just going crazy and yelling and screaming in anger because of a little incident or for no reason.

Me: I was hanging out with Brett earlier but then I left.
Friend: Why?
Me: He went from zero to sixty in like two seconds because I beat him in a video game!

Sixth Guns 

It originated from the name of their tour 'Nameless Liberty Six Guns' where the Vocalist Ruki described five out of six being held by the members of the band, while the sixth gun is held by the fans because "Nameless Liberty Six Guns" and "Nameless Liberty Six Bullets" were public and not only heresy tours.

We're the sixth guns!.
