A woman who may or may not be a "whore". Definitely a skank, but not quite a slut. Usually STD ridden and is often viewed as a "bitch" but is often a "trick".
A scut is a second cousin to the smut family. A scut is a female who comes off as classy and as if she has morals, but is really a slut. A closet or secret slut. (Sc for secret ut for slut). These females are taking a threshold of America. They will fool you.
a long ass time ago someone called someone a slut (they were 9 and 13) so one told the mumand the other changed the l to to a c by adding a = thus scut was born
