moccasins.

An admittedly stupid new inside joke on the (once-)popular Wikipedia parody website known as Uncyclopedia (en.uncyclopedia.co). The joke began in an article titled "A story built one word at a time" (in which, of course, an editor could only type one word into the article before waiting for someone else to do the same). In this story, these shoes were by chance referred to as swag, eventually leading to the word "moccasin" being spammed all over the story and elsewhere on Uncyclopedia, often in giant bold letters.
Large amounts of moccasin lore now exists on Uncyclopedia, such as a the existence of a nation called Moccasinia ruled over by the Great Lord Móckasiin (I can't make this stuff up), and the all-knowing Supreme Skin-Shoe Deity Mokkááwŝen.

WOW! Willy Wonka can shit! That's how I died. Remember the penguins at the chocolate factory? They pushed Mario, then jumped onto a pregnant Luigi in hell, also moccasins kill moccasins just because moccasins kill moccasins moccasinly because of fucking
(in giant bold letters) moccasins.
