When a guy or girl, mostly girls at Sulphur High School, crave the attention of the opposite sex with a passion. Signs include this person consecutively liking pictures of you on Facebook, messaging constantly, etc. This feeling is usually not mutual, making it more annoying.
Man, I've got a date for homecoming already and she's still stalking my Facebook. She messaged me to ask if I wanted to go to her after party; she said she doesn't even know who else is going to go yet. She's so thirsty.

A term used mostly by fags. To these fags, "thirsty" means desperate. They know the meaning of this word because the only chicks who actually get with them are thirsty and desperate as hell, and with apparently no standards.
"Hey, that girl is so thirsty desperate ! Reminds me of Taylor's last hook-up."

When a girl is so obsessed with what another girls does and she won't leave her alone. What the other girl does doesn't even concern her, and it's not even a big deal but the thirsty girl just won't leave her alone.
If a girl works at a restaurant and has to wear lingerie for a themed week, the thirsty girl is so jealous that she can't dress like that and make money so she bashes her for no reason
