A leaper is a person who has a lot of friends but no close or best friends. You usually see them at lunch going from table to table sitting only minutes at a time with each group of friends. Leapers can be popular nerds.
Leaper is the term used to describe the non-canon ship of Leah Clearwater and Jasper Hale from the Twilight fandom. It is a portmanteaux of 'Leah' and 'Jasper'.
Pippo: Omg, I read this fanfic the other day that shipped Leah with Jasper -
Fippo: Jasper?!
Pippo: I know, I know - it's random, BUT it's really intense. They would make such a good couple. Leaper is my new OTP.
