a semantically empty suffix that creates informal variations of more neutral nouns and adjectives by processes of truncation identical to those of -er7. (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.
Origin
perhaps a conflation of -er7 with the final element of bonkers and crackers (unless these words themselves contain this suffix); cf. -s3
