An expression that's used when something is extremely cringey or not acceptable to have an existence. This term is mostly overused because of some angsty white teens trying to be chill.
Correct use:

"musical.ly is the pure cancer of the world."
"This post on Instagram is so shitty that it could cause pure cancer."

Incorrect use:

"My mom has got pure cancer and now she's been brought to the hospital for research."
