columbine crew 

that group of 7 or 8 goofaces that hang around your local coffee shop/venue on open mic night. they wear an excessive amount of black, never break formation, and will make even the most self-assured fellow very uncomfortable. they tend to pick an inconvenient spot, such as a narrow walkway or the only couch or pool table in the building, and stick to it for hours. they're ultimately harmless, but creepy nonetheless.

geraldine: "ohhh fuck. columbine crew on your 6."

bertha: "man, let's dip."

Columbine any % 

A speed-run that involves an in real life manhunt for a victim where the time stops when the victim is dead

After performing the Columbine Any % I bet the time could be lowered to a sub 5hr paced run.
