>>108198087kekaroo is a word invented by the dragon ball super general from /a/, made to denote mocking laughter. It is a mxiture of "kek", a commonly used 4chan lingo synonymous with "lol", originating from the popular MMO video game World of Warcraft, wherein the word "lol", when typed by horde players, would be turned into a "kek" when seen by alliance players. The -roo suffix means nothing in particular, it's just there because it's a common suffix and to make it as annoying as possible, as was the culture of the general tjat birthed.
Peamaroo is a recent /vt/ lingo meant to mock the use of "kekaroo" by bringing up the Australian marsupial animal known as kangaroo. It is a mixture between "peam", a deliberate misspelling of the word "peak", and kangaroo. It has at times been used as an affectionate word for kangaroo.
