Short for "distribution", as in Linux distribution. Some examples are Debian
GNU/Linux (heh heh heh), Slackware, Red Hat, and SuSE. If I've left your favorite distro out, then TFB; all flames go to C:\WINDOWS\SYSTEM\null.vxd or some such place.

As in a person or persons who distribute(s) records locally. Unfortunately, economic times during the
Reagan, Bush Sr., Clinton era were tough on some American kids, punk and hardcore were
tainted by the music "business," and many of the people who ran distros and labels are now in debt.

distribution = D = disusered

distro n.

Synonym for distribution, sense 1.
