Once I thought it was just a common misspelling, adopted for humourous purpose too and also eventually become a brand name, but I just found that "duck tape" is also a correct name for it, coming from a particular cotton cloth initially used to produce it.

Obviously I still prefer its use as intentional misspelling.
