From a tweet by Donald Trump on May 31, 2017: “Despite the constant negative press covfefe”, presumably intending to write coverage. Donald Trump later tweeted: “Who can figure out the true meaning of "covfefe" ??? Enjoy!”. Sense 1 ("deliberate misspelling of coffee") is from the phonetic similarity.
