Scawoo is a word used for many things, a common way is to use it among friends, to call out to them, so that you can find them if lost. Also use to just throw it into a sentence when you feel it's needed.

It can also be compared to the word "Suwhoop" Used by Bloods but by taking it and adding a C to it, the Crips use it, making a mockery of them. As they know they can't be on that brip shit.
