Radioactive Fireflies 

Large, extraterrestial beings who are from Outer Space. Those lucky enough to be able to communicate with these large bugs are able to command them to rape people they dislike up the butt.

If you ever do that again, I'll send a firefly after you.
I hope you like insect penis, a-hole.
Radioactive fireflies are the shheeeeeeeiiiitttt.

radioactive queef 

Much like a normal queef , but with a rotten quality that will make your hair fall out.

Did you see Joe shaved his head?

No, are you sure Brenda didn't let out a radioactive queef?

Radioactive Carp 

Used to describe females originating in and around Niagara Falls... specifically Welland.

You can usually find them around the canal. With hair of unusual colouring... typically Green. They usually have many piercings... they use as trophies for all the fishing lines they have been freed from. They typically have an inbred look to them, the odd one may resemble an angler fish; with similar teeth. These carp are triggered easily and will attack; if you call them out on their stupidity, sleep with their man (who they also borrowed), or throw maggot water off your balcony.

“Hey bro, look at that radioactive carp over there, she’s the type a girl you pull the fuse out of the heated seats for”

Radioactive immaturity 

When a video, book, film, person etc. is so immature, it's almost radioactive.

"That new try not to laugh video had so many stupid jokes in it, it could be considered radioactive immaturity!"
