24 is an Arizona straight edge crew who is infamous for dancing at shows. They find themselves to be xtuffx because they can snap little scene Scottsdale kids in half with their windmills. They will take up the entire pits and beat kids up just because they accidently hit them. They are straight edge supremacists and overreact if anyone makes the decision to smoke or drink. Hardcore Mike is the founder. They are notorious for wearing basketball shorts and jerseys with 24 on it. They are a dying breed.
Innocent Kid: hey, do you have a light for my cig?
Hardcore Mike: DURP DURP! 24, ATTACK!
(kids gets roundhouse kicked by 15 24 members who are Hardcore Mike's bitches)

Scottsdale Scenester: wow! See You Next Tuesday has another breakdown, I am going to dance!
*proceeds to dance*
24 Crew: WE DON'T LIKE THIS KID!
*they proceed to 2-step overr him and kid gets sent to hospital*

Different acronyms/words they use: AZHXC, AZSXE, Straight Edge Soldiers

a crew of straightedge friends who stick up for themselves and their friends. x is the 24th letter of the alphabet-->x24x=xxx

no drugs, no drinking, no smoking, poison free.

*Being clean doesn't necessarily make you better than everybody else but if you're sloppy wasted and get your ass handed to you maybe you should rethink some decisions.*

the get a bad rap from people who don't know them but on a whole they are nice ass dudes.

If you hit one of them or one of their friends they will probably hit you back, just like you would so stop whining because they are bigger than you. If you don't like being in a dangerous place maybe you should stay out of hardcore shows and go watch Justin Beiber.

Its a family and families look out for their own.

The 24 Crew is A "crew" of assholes who go to hardcore shows and beat kids up.
Most of them have huge gages in their ears and wear baseball style shirts with 24 on the back.
When Moshing if a little scene kid hits them they beat them up.
Very straightedge, and will beat up people smoking.
"Omgzzz, when I was doing my windmill in the mosh pit I accidently punched a 24 and the messed me up."

"Ow, the crew just beat my girlfriend up for me smoking."

"Eww, That 24 Crew kid totaly made half of my face bleed like crazy."
