A madam of the nasty ghetto species, dressed in an ensemble of cheetah print leggings and a leotard, not to mention the thong 4 sizes too small beneath these items. On top of her head is generally perched a purple weave, often resembling shredded plastic. A lady of this sort may be caught sipping a beverage called Baby Drank, or 4loko mixed with rufies......... AKA Baby Drank. Ratchets are most commonly known for their slurring of words due to the Baby Drank. Most Ratches are commonly found dancing sloppily on poles, most commonly knocking them over due to their immense weight. A Ratchet is also commonly found on the arm of a big black man smoking a cheap cigar.

Ratchet babies are a rare breed of child raised but the most ratchety ratchets. Such a creature drinks a mixture of Baby Drank and Heroin for nutrients. This habit is started from birth to build up tolerance for the (short) life ahead of him/her. A ratchet laugh is usually high pictched, sometimes to a frequency most people over 40 cannot hear.
