A kit used to attain straightness of hair. Used to get rid of what we black folks call "naps". It presents a false sense of neatness because if you don't keep using it, the waves dissappear. Not to be confused with the waves that are acheived when using a brush, grease, and a durag. S-Curl waves are pretty but fake.
Nigga #1:Did you see Ray Ray's hair?
Nigga #2:Yeah it was wavy!
Nigga #1: That shit ain't real, that nigga got an S-Curl yesterday.
Cassidy: I like that curly little hair strand on your face.
David: Thanks. I like your pigtails
Cassidy: Thanks, btw lets call that curly hair strand a David's Curl.
David: Sure.
This happens if you get really wasted at a party and end up in bed with a lumpy sausage-shaped woman. When you scurry to the door you find that it is locked (hence scur+locked) and only she has the key. Thus you end up spending the night with said lumpy sausage woman. Shame on you.
Guy1: Fuck I was so high last nite I ended up with Fannie. I tried to leave but got scurlocked!
