The popular meme, "Top Donkey" was created by a group on Kik, #memefactory on July 4th 2015. The meme is similar to "top kek" and means the same thing, excepting "kek" is replaced by "donkey" An image accompyaning Top Donkey is usually a picture of Shrek or Donkey.
A member of the group, Nick "TFW_no_gf" posted the first "top donkey" thread on 4chan. The point of Top Donkey was to replace the common 4chan phrase, "top kek" After the succession of the first post, fellow user TheRoosel, iZarek, and PeePeeHelicopter added multiple threads to the new meme. Several also made posts about it on the comedy app "iFunny" to encourage their many subscribers to take part. The Meme has since lost popularity, although being considered a large part of the iFunny community for a time.
