Mariana 

The funniest, prettiest, coolest, smartest, most awesome person ever. She pwns you at school with a 3.9 GPA, pwns you at video games having beaten Paper Mario 2 six times, pwns you at awesomeness with her existence, and just pwns kthnx. She has no life, but that's okay, because her awesomeness makes up for it. She makes her friends lol on a regular basis, because she's cool like that. She's crazy and basically nothing scares her. She also hates surprises, so don't even try it.

That girl is amazing! Definitely a Mariana.

Mariana 

Amazing, wonderful, beautiful chick. Mariana's are very giggly, funny, and fun-loving. They are extremely ticklish and smell very nice. They are also secretly defiant (they usually have dyed hair, piercings, or a unique fashion sense). You must always approach a Mariana first because they will rarely approach you. Mariana's have killer eyes and a beautiful smile/laugh. They have unique interests and laugh at your passions but secretly admire, respect, and adore you. Be sure to stay close to them because they tend to be cold all the time and need your warmth and affection. Talk to them about deep intimate thoughts and stories; they love that shit.

Me: Hey, Mariana!
Mari: (laughs)
Me: Why, what's up?
Mari: Your face, goddammit! (laughs)

Mariana is such a bitch ass cunt, she is so fierce and has a bad temper. She can be hilarious at times but don't get on her bad side. She also can't catch a man, she will always be single for the rest of her life.

That new girl is such a mariana

Mariana 

Here's a real, non-biased definition:
It's a person's name, and it means maiden of the sea.

Hi, Mariana.
