A phrase used to describe people of any age who are socially unacceptable. They usually are emotionally unstable, prone to fight to solve problems or have lots of sex with other rat kids. They like to brag about the awesome party they went to where they got totally smashed (a.k.a. Their mom's birthday party where they sneaked a sip of a wine cooler) or the hot girl/guy they banged (aka their hand...) They are liars and exaggerators by nature, and their appearance and dress only serves to emphasize their ratty nature.
Can generally be found in lower-level classes, or in a grade that doesn't correspond with their age.
Originates from an advanced biology class in describing the group of people in the class after them.

Get the Sewer Ratmug. When a girl sags her pants so low you can see the top of her thong, aka underwear that has a string in the back for your asscrack.
Usually happens to girls in junior high who think showing their big-girl underwear makes them cool and attractive.

A Guinea Pig... A vile little creature that resembles nothing so much as a rat, if that rat were designed by GM and built by AMC.
