Soo-woop is wrong. you need to check "soo woo" because it is the correct spelling. Soo Woo is a blood call just like what it do at first. what it do is now used more loosely not associating the bloodz.
Blood 1: "Soo-woop nigga!!"
Blood 2: "Na nigga its soo woo. lets whoop this crab ass nigga anyway!"
