People at my school who don’t know how to shut up. A rat is basically someone you don’t like at all.

An amazing friend, usually found on the internet. They usually come in groups of six or seven, and are most commonly Irish. They prefer to stay inside, only leaving the safety of their homes to meet up, running amok in shopping centers and/or the city. Can be found together, or chatting on their phones.
"Oh yeah, I met up with the Rats on Saturday, it was really cool."
OR
"Did you see what happened in the Rats groupchat? Omg check it out we're all wheezing!"
OR
"Oh sorry Mam, I'm just getting a call from the Rats"

A rat is the lowest human being to walk this earth. A rat usually does a lot of drugs (oxy contin/ heroin), has no money, has no job, does nothing with his/her life, but look for the next high. A rat is just a grimy, worthless, lowlife individual.
