I wonder if the verb “pink”, to thrust, came from the verb “potch”, meaning to poke or thrust at (Shakespeare, Coriolanus Act 1, scene 10)
Evidence suggests that a new verb "pink" -- a synonym of the verb "pink-slip" -- is also emerging.In this sense, we need to have a massive pinking of the House and Senate in November 2010, and an overwhelming pinking of the White House in November 2012.
