An imaginary flute that, when played, signals the presence of one or more "sloots" (sluty women) in the vicinity. While playing the imaginary flute you may make the sound "Sloo-ta-loo" to let others know there are sloots in the area.
"dude, last night the sloot flutes were playing loud and proud!"
"Sloo-ta-loo!"
Another reference to when two dudes try to stuff both of their man meat into a chick's pussy. I'm not sure where the origin came from, but I heard the term used on Eminem's response to Mariah Carey's "Obsessed".
"...When me and Luis were tryin to stick two CD's in the same slot."
Sloot is the basic word. The more O's in "sloot", the sluttier the girl is. 2 O's is the minimum, you can add as many O's as necessary to add emphasis to just how slutty the girl is.
That bitch? Her and her friends are some slooooooooots, let me tell you.
a skeezer, slooter, whore, bird-brain, pigeon, skeeo; just a straight cock teasin', pleasin' kind of broad that will take a dime for it or just do it cuz she loves the cock; men and women alike love their company at parties because a little extra alcohol will make their pants fall and will have serious rug burns on the knees...sloot whores are loved by most, hated by most other women, but do a job
this sloot whore just got the train ran on her at Jason's party last night; then she has the nerve to call her sloot whore friendJamie to tell her she should have joined but Jamie was blowin' me already
