low key slut
A girl that is a kind person that does not dress or act like a slut, but hooks up and fucks different guys almost every weekend. When confronted with being a slut, a low key slut will usually say, "It was only that weekend" or "I didn't think anything would happen until it did" or "I wasn't thinking straight that night" or "don't judge me based on one night" or ask why you are so interested in her life.
Person 1: "She seems like a nice person". Person 2: "She is, but she's hooked up with 6 guys in the last two weekends dude". Person 1: "Damn she's a low key slut then".
