It's a term used by Uffie in her song, Pop the Glock. It means one can drive with his gang/or people. Usually, the people are just known as a car not to be messed with...maybe they are part of a gang or they have drugs or they will just kick someone's butt in general.
"Me and He are crusalicious, better watch out our clan gets vicious."
or, for a non-lyric example,
"Girl, don't go by that red car. They be crusalicious."
