That post gave me cancer 

A post on an image sharing site like 4chan or a forum that is so utterly terrible that it gives someone cancer.

You just gave me cancer 

The phrase you tell to a person when something about what they did or said tortured the very fiber of your being to such an extent that you felt like you just got cancer, but wanted to bring that fact to light in a chill, joking, almost passive-aggressive fashion.

Friend: I think I'm going to buy a scooter. I spend too much time walking and it would make me more productive.
Me: Cool bro, there's just one problem... You just gave me cancer.
