I keep hearing his dad is native american or sum shit. I know some nigs in brooklyn who claim his uncle was black though (which would mean his dad was black) but hey. Plus dude seems to be too dark to be half... but you never know, black genes are weird. i've got hispanic blood (1/4) and an african dad but I'm pretty brown.. so we'll never know...
and i know people called ramon (usually pronounced like raymond)
EDIT: in this video they show his dadhttp://nahright.com/news/2009/09/15/video-bet-rising-icon-kid-cudi/
if that helps
