You start a prank war, and it's normally because you're confident in your abilities.. not because you're scared or think you might PASS OUT. 

This guy got so scared by what was in his apartment that he fainted and then sobbed like a 5 year old boy. 

He made this statement afterwards: 

"The whole world of 'evil spirits' terrifies me to no end. So, Yes. I did cry. hard. But come onnnnnnn. I came home to my empty apartment under the assumption that I was ALONE....I cried because when I woke up I had no idea what was going on. I was confused and to be honest fainting is scary. At the end of the day, they're my homies and all is fare [sic] in love and war. And I did start a prank war with Ahmed. But I told them.. THIS IS MY CHANNEL. Stop trying to get me. lol."
