Another word for erection. Originated from getting boners in school everyday around 9:30. You can walk around with it down your leg to show everyone, or you can tuck it under your ass if you're ashamed of it. When your boner is limp and no longer of value to your sexy ass teacher, it is called a "9:31".
When the fly ass whore sat on my dick, I felt like it was 9:30, so she fucked my dick 'til I busted baby juice.

The perfect time (PM) to have a huge party to celebrate the end of school and the start of summer while your parents are out of town for the weekend. Just make sure the beer delivery guy doesn't arrive early and blows the whole plan, know what I'm sayin'?

Made famous by Richard Linklater's 1993 movie "Dazed and Confused".
Slater: "What time is your party tonight, man?"

Pickford: "9:30, man"

Slater: "9:30... Mmm.. Okay.. I'll be there, man"

Legendary Washington, D.C. music club, founded in the 1980s, and originally located on 930 F Street. The location has sinced changed to 815 V Street, which allows the nightclub to house up to 1200 people. Bands large and small play at 9:30, and the tickets are often inexpensive, which allows even teenagers to afford to go, keeping up with the motto: "All ages, all the time." At its first location, the venue was nicknamed "the dirty 30," because of its 'distinctive odor.'
