Buttercup
Michael Avenatti, the lawyer of adult movie star "Stormy Daniels" (real name: Stephanie Clifford) against US President Donald Trump's ex lawyer and "fixer" Michael Cohen used on 29 July 2018 the phrase "You better buckle up buttercup" in a tweet addressing Donald Trump's lawyer Rudy Giuliani, which soon became the hashtag #BuckleUpButtercup.
