KSI

Some shit hole who beats up people in a box with wires surrounding them and then somehow wins. he even says some words with some instruments playing sounds in the background and he says the word in a tune. he sucks at both.

Theres people like Swarmz who should get more recognition, hes the coolest person in the world, Hes so good at rapping and boxing no one can do anything to him. KSI sucks!

Man: Hey bro do you know KSI.
Man 2: Yeah, Do you like him?
Man: Yeah, hes kinda funny
