chiminology
Speech or writing marked by overly complex vocabulary.
rare, uncountable
You've been talking chiminology on about fuck knows what for, God knows how long.
Where it comes from
From cheem + -ology on analogy of -inology words like criminology and terminology in which the -in- belongs to the Latin oblique stem, the former from either Hokkien 深 (chhim, “deep”) or Teochew 深 (cim¹, “deep”).
