A Scraw is a "Go-To" WHITE friend who is; talented, reliable, intelligent, and seems to always be at the right place at the right time.
(while waiting in an obscienly large line..)
-You: "I forgot my wallet in my car."
-Typical 'Friend': "Well, go grab it. I'll hold our spot in line."
(Just then, a Scraw arrives unannounced and right on time, as usual.)
-Scraw: "Here, let me spot you some cash, you can just get me back later"
