Other forms: pranksters
A prankster is someone who loves to play tricks or practical jokes. If your house gets rolled in the night, a prankster hung toilet paper all over the trees in your yard. Congratulations?
To be a prankster, you need a mischievous sense of humor and enough imagination to dream up practical jokes. You could glue a ten-dollar bill to the floor, change your sister's computer settings to Portuguese, or leave your fake bug collection on your teacher's chair. These tricks or hoaxes are also called pranks, the origin of prankster, which probably stems from the obsolete verb prank, "decorate or dress up."
