Literally giving your heart to someone for one day in February... if they accept, they are known as a "Valentine".
There are several different ways to ask:
1. The "Grade School Method" - Will you be my Valentine? Check YES NO or MAYBE 2. The "Charlie Brown Method" - Creating a hand crafted and laced heart shaped Valentine's Day card to the one you love
3. The "Tiffany Method" - Utilizing a popular public website to give your heart away. *see example*
You make me want to break every rule. Like the one that says when you play that flower petal game you have to alternate "I love you's" with "I love you not's" ...and the rule that says that only certain people are meant to be together...
Valentine is girl who many people know. She was born on Valentine's day, or near Valentine's day. She is most likely very funny and beautiful. In fact if you happen to be friends with a Valentine you should probably feel very priviliged considering she is one of the most popular girls in the school/ workplace/ etc. because she is very pretty so all the girls are jealous, and all of the boys are obssessed with her. Also she is probably really smart, so the teacher's all love her.
Casey: Oh my goossshh Valentine is like, so pretty, im so jealous :(
Super Hot guy: Dude, I would tap that
Teacher's: A+ again Valentine! Gosh you're so smart!
The New Year's resolutioner's that join a gym or healthclub in January, hog the shower and weight machines...and then will stop working out by Valentine's Day.
