A phrase that is also use as a snitch, such as also the rapper 6ix9ine, people often calling him rat because he snitched on other rappers or even gang members so that he doesn't get arrested, but now he's out of jail.
But today many people use the word rat to call out any nerds who snitched on them and then later smoked them like a chimney.
Nerd: did you just insulted my gender and insulted my fictional character!? I'm gonna tell Ms. Kimmy Hed
Cool dude: Ok what ever you say pal, you's a rat anyway. hope you have trials and tribulations.

Get the Ratmug. 
A person who exposes another person's wrongdoings for reasons other than moral outrage or to seek justice. Usually for personal gain, to avoid trouble themselves, or out of jealousy.
The word is sometimes misused by highly immoral people to describe all people who provide incriminating evidence against other people, simply because they dislike the idea of being exposed, and want to associate a negative word with people who expose immorality.
