to look worn out, torn or dirty.

short for ratchet, used when someone is on a shooting streak in basketball

An affectionate term for a rat, most usually domesticated. It has no relation to the general use of the word 'ratty' which describes a disheveled appearance.

The term used to describe the hairstyle in which an elongated segment of hair which is more often than not awfully greasy and encased in dirt and stale urine, hangs from the back of the head, starting from below the ears. A 'ratty', or rat's tail, is traditionally never longer than the shoulders, yet it is not uncommon to see longer specimens. This style is appropriated in Australian fashion among bogans, ethnics, and lads. While common, ratties are not considered appropriate workplace fashion, hence their residing on the heads of less work-inclined individuals.

Ratty is like… sweatpants all day, bad hair, eating lots of crappy food – it’s basically a term of endearment if you are doing something gross, but at the same time, it’s totally acceptable.

Something that would be referred to as vile, putrid or repulsive. Something that is disgusting and makes you feel sick.
