Meaning of -ERS in English
a semantically empty suffix that creates informal variations of more neutral nouns and adjectives by processes of truncation identical to those of -er 7 ( champers; preggers; starkers ); unlike that suffix, however, -ers is apparently productive, and words formed with it do not appear to belong to a restricted linguistic register, as university slang.
[ perh. a conflation of -ER 7 with the final element of BONKERS and CRACKERS (unless these words themselves contain this suffix); cf. -S 3 ]
