sherk /'sherk'/ (noun) someone who both shirks responsibility to do their own
work and steals credit for another person's
work, especially to advance themselves at the other's expense.
Etymology: triple portmanteau of "shark" (in the sense of a predator of other's efforts), "shirk" (to avoid
work), and "jerk" (a contemptible person).
"Katharine Parker's character in the 1988 film 'Working
Girl' is a canonical example of a sherk, an unscrupulous boss who steals her employees' ideas and claims credit for their work, while contributing nothing of value herself."
"Republican Senator Roger Wicker of Mississippi, who voted 'no' on the $1.9 trillion
American Rescue Plan, later tweeted that he deserved credit for passing the widely popular
bill, confirming once again that he is an 'odious sherk' as his critics have charged."
