1.
An incredibly seductive and sexual being.
She is intelligent and caring, very loving, and a great friend.
She won't take shit from anyone and will make it clear, though she is very open-minded towards almost anything.
She adores the band Coldplay, almost more than she loves her boyfriend, but it's all good because she's his one and only and he loves her more.

2. The act of being extremely sexy.
"Dude, have you seen Yanessa?'
"Yeah bro, she's fucking gorgeous"

"Hey man what's going on?"
"Not much, my girl turned into a Yanessa last night"
"Lucky bastard!"
