Modern Toss was invented in 2004 as the label for a series of cartoons by Jon Link and Mick Bunnage. I assume the title Modern Toss coincides in meaning with an entry in the Oxford English Dictionary from 2007 giving an ‘additional sense’ for toss. But the OED also points to the phrase not to give a toss, cited from 1876, in George Eliot’s Daniel Deronda: ‘I don’t care a toss where you are.’ ‘They took to hackwork in literature, and decided by the toss of a halfpenny that Concanen should defend the ministry, while Sterling was to be in opposition.’ Whether to say toss or flip now seems just heads or tails.
