Serena

is one sexy mysterious girl that every guy wants. She acts bubbly on the outside, but has a hidden dark side that is so evil and so sexy it makes everyone partially terrified and partially turned on. A Serena seems innocent, but is crazy hot in bed.

Don't mess with her, she's a Serena.

-Dude, dont blow us off for a girl.
-She's not just a girl, she's a Serena.
