A fun nickname fans of Gossip Girl gave the show's main character, Serena van der Woodsen, played by gorgeous young actress Blake Lively.
Why? Because on the show Serena usually gets laid every episode and usually falls in love with 5 guys at a time, therefore being considered a slut by many real people as well as characters.
The second part of the nickname is due to the fact that the actress has great looking boobs (the reason why some guys watch the show, unless you like the "story"), which are at many times showing during the show.

*Note that Blake Lively is not being called a slut, only the character she plays on that TV show is under that nickname.*

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.
