This reference term is not universally used, but is more widely popular by reggae listeners in California; notably the Southern California regions.
"This Rasta tune is sick!”
“Hugh Mundell was a great Rasta singer!”
Rasta 'til the day I decay! I'm Rasta because I love life and I'm trying to better myself as a person and opening up those eyes that are closed. Rasta is education, Rasta is love, Rasta is fighting oppression. Rasta is the positive nature of life! Let them talk of my ganja smokin', let them talk of my non-conformity- I listen to my soul, not what someone tells me. Love God, Love Life, Love Soul and look past the ganja smoke in Bob Marley's music. Please.
n. referring (incorrectly) to any person having dreadlocks
There are some "poser" rastas, that only call themselves rastas, so that they can dread their hair and smoke weed.
The smoking of weed is considered a way of speaking to their god, Jah. Rastafarians do read and follow the bible, and they helped shape Jamaica's people nowadays.
They use the bible, but don't really look into the Jesus part of it.
They might have dread locks.
And most use weed to connect to Jah in a new way, and see stuff in a diffrent light.
"Bob Marley is fucking Rasta! But George Bush is fucking not!"
