I got a weird message on kik

[AC Question]

i got a weird message on kik that looked similar to this http :// pastebin.com / 34sH0DKz but it made a big fuzzy chacter on my android but the person who sent it later said "lmao It works" after he sent it a few more times. this person in the group is know to like to screw with people so i was wondering if i should be worried
i googled and searched every where for the text but couldnt find aything i mostly got a 400 error until i shortened it and searched and it pulled up PasteBin
