The relational opposite of 'keming' is ⬛. ['Keming', incidentally or not, might be a more amusing coinage if aged eyes could distinguish between 'kerning' and 'keming' in at least one of the atrocious fonts used for IE on old Windows systems.] This relational opposite, ⬛, makes more sense than 'ker_ning', an opposite coined in apparent ignorance of the one true and unassailable definition of 'keming', which is
the result of improper kerning.
That definition was supplied by the coiner of 'keming' at the Ironic Sans blog, as mentioned in an entry called "Keming Revisited".
As can readily be seen, ⬛ is the result of tracking or letter-spacing gone wrong. Before the tracking was improperly applied, the paragraph it was applied to read as follows:
'Kippering' is the typographical term for smoking, or otherwise applying heat, a chisel, or acid to a block of hot-metal type in order to make it all run together or break apart. More recently, 'kippering' has been accomplished with electronic means. An example of the latter is the early X Window screen saver application which, when installed, caused any letters on the display to gradually and randomly break off and flutter like falling leaves to the bottom of the display, where they accumulated in a black, snow-drift like heap.
