ankle slasher
People who hide under your car in a parking lot or other parking space with some long sharp object (like a sword) and slash at your ankles to cripple you and then hop out and rob you, or rape you, or take whatever you want, cause you are in pain, and can't move from the ankle injury.
Jeff wanted to rob the poor old lady who was shopping in Wal*Mart, so he hid under her Lamborghini with a sword, and when she walked by, he slashed her ankles, and snatched the purse full of ratchet money. He snatched the ratch, cause you know, if it's ratchet, then you snatch it. He was an ankle slasher.
