"Man up!" in lyrics
Take it how you want it, get mad when you get it
Blame everyone around you for the money you ain't gettin'
Boy man up to the life you ain't livin'
Times get chilling, sometimes I forgive him, my minds on a rhythm, so get the fuck up when I see you
My Kypro (I am guessing it is the name of the man, however it also means Cyprus), for a laughter of yours
I would give my man up for you (However here it seems like they are talking about the country and a soldier)
Only with you I would accept
That's a gray ghost, with the ears on it
Swimming through the hood like it got fins on it (Tell 'em!)
You know I got that work on the foreman grill
Weigh the muthafuckas in, made another mill'
