A very Caucasian way of saying "not now" ; not partaking at the moment; holding off for another time; maybe later.
-Hey Lucas, would you care to come with me to West Jacksonville tonight? I'm doing a sociology research project on how African Americans live and do not want to go alone lol.
-I'm going to have to check the rain on that Abigail, I'm in no mood to get stabbed tonight and have no money for crack even if I was. If you want, just come over to my house, me and Brett are just cool lampin by the beach. And by the way my textbook reads that not all colored folk are from Africa.
