Simply, a cold tough woman, especially one who leads men on, have their fun and then ditch them. Also, it's the title of a 2004 hit by the band Jet, which hails from Down Under.
Ami keeps leading Keith on, they're both blitzed, but she's gonna get all she can from him and then drop him like a rock. She's a cold hard bitch.
