look up any word, like demisexual:
A boyfriend/girlfriend that you have for only one day: Valentine's Day.

In other words, it's the socially acceptable one-night stand.
I asked Jenny to be my valentine. I'll be all lovey-dovey to her today and totally forget about her tomorrow.

What you call the boy/girl your temporarily "dating" for Valentine's Day. Something invented to make the rest of us single people feel like lonely shit.
I wish I had a Valentine.

A valentine is a person that you want to spend every day with, especially valentines day. If you dont spend valentines day with your valentine (for example, if it was your sister's birthday and you were forced to go see her and not the girl that you really wanted to see) you would be a wreck trying to find ways to apologise to that "special someone" and trying to think of exactly what would be the right thing to say. Then you might end up doing something strange like posting something on a website at 4 in the morning to try to show that person you care. Then after reading what you put on the website, that person may think you're completely insane and never talk to you again. Or they could make your day. We'll see what happens.
So, here it goes. Megan, will you be my valentine?

Spending a day with someone because the person you want isn't available. A day to remind everyone of those you cant have, or gave up.
" I'm washed up, I wish she could be my valentine."

A person who is absolutely wonderful and makes your life better just by being a part of it. Someone who makes you happy. Someone you care about and know you can count on. Someone who likes you no matter how silly or weird you are.
Dear Jennafer, obviously no one could be a better valentine than you. Boy meets world marathon when I come home to you this weekend? Kthanksbye!

a person who you find to be mysteriously attractive, or doesn't like you but you persist on going after her anyways.
