theater rat 

a pretty cool person who loves theater and its a lifestyle. they make lots of musical references even if you don't understand and constantly burst into song. it's contagious and soon you as well will burst into song. if its a female then they generally are super sweet and for the male species not only are they likely gay but honestly kinda hot... a theater rat can also have a cute nickname as "pip-squeak" and if they like cheese to be sure to bring it up at least once.

wow, that girl Iyar is such a theater rat! I love that! they are my favorite type of people!!!

Cairns rat 

The lowest of the lows of the cairns species. Cairns rats usually reside in the beaches OR far south. They generally congregate at bus stops or centralz. They carry duffel bags and wear baggy shorts. They have that general ‘crusty’ and/or ‘greasy’ look to them that makes all the non-cairns rats spew. A cairns rat proba went to smithy but you’ll find they are pretty good at getting into the private schools round here too- you’ll find some at TAS. If your a cairns rat you stay in cairns after graduating (if u even graduated u probs just dropped out after grade 10) and live with ur parents and eventually become a tradie with a mullet- this is not to be confused with a eshay which is a notably different breed.

Oh look here comes a cairns rat, ew it smells 🐀🤮
