Niggas from where I'm from they don't fuck with fights
When it's trouble, they "blocka" and fuck a life
For a fuckin' Nike or a couple sprites

from Wale – Purple Swag (Freestyle) Lyrics on Rap Genius

Meaning

Dudes from D.C. don’t fight, they just shoot out over a dispute. Wale’s commenting on how ridiculous this is, that dudes in his hood are getting killed over such trivial things as a pair of sneakers. It was rumored that a D.C. citizen was killed over a pair of Jordan XI Concords (which was later proven to be a hoax.) Someone’s gotta get Wale up to date on current events!

“Blocka” is an onomatopoeia for the sound of a gun shot.

While there was no killing over the Concord XI’s, there was in fact a killing in the DC area over a pair of Nike Zoom Rookie LWP. This is not uncommon in the DMV (DC/Maryland/Virginia region.)
