Just caught, a Swiffer commercial in which a mother wields her Swiffer to good effect, starts taking a Cool Mom Test, and asks her two kids,
Do you guys think I’m mom-tacular or mom-trocious?
(they roll their eyes pityingly).
Modest number of hits for mom-tacular, with the libfix -tacular (recorded by Grant Barrett in 2005, with some forms going back to 1958). But mom-trocious looks unique, still at the portmanteau stage, but set up by mom-tacular.
