A high powered bitch, usually with a hyphenated last name. These women hate men and are snake killers.
Have you seen that new chick in legal? Yeah, her last name has a hyphen. That bitch is a power hungry mongoose.

Get the Mongoose mug.
A person who flirts with as many people as possible, and then rejects those who inevitably fall in love. Stems from an unhealthy low self-esteem, as they want to feel loved by as many people as possible, regardless of whether or not they actually like said people. Originated from the idea that people don't know whether a mongoose eats a snake or a snake eats a mongoose.
1 - I think I've fallen in love with you...
2 - Oh... well, sorry, I don't feel the same.
1 - What? But you've given me all the signals!
2 - Oh yeah, haha, I tend to do that. ^^
1 - You're such a mongoose. :'(
2 - Excuse me?

I did The Mongoose in the locker room today before football practice. My friends all shared in horrified laughter

Like the vehicle in Halo, a mongoose is that one bro who every girl knows is there but no one wants to ride.
"God, there are like no guys at this party"
'What about Mike?"
"Nah he's such a mongoose"
