Once you post something on social media, someone, somewhere, is most likely going to hold you to what you said. 

This is the case with KSI, a rapper and youtuber from the United Kingdom. 

On December 14, KSI hit Twitter to claim he will never get Covid, and just two day later, he tested positive.

I will never get covid.

Suprisingly, he hasn't deleted the tweet, so he must not care.
