Word History

The Combo

deadass passionately Deadassionately

lend (portmanteau) of the slang intensifier deadass ("in complete earnest, without joking"; itself dead + ass as an intensifier) and the adverb passionately. The fused medial -ass- + pass- yields the surface form -assionately-. Coined by Professor Sendy, who demonstrates the term as the seed of a recursively expandable compound, accreting the rhyming suffixes -spectacular, -particular, -lenticular, and finally -lowkirkentologiclowstatothenticlaura to produce escalating maximal forms (Deadassionatetacular, Deadassionatetacularticular, Deadassionatetacularticulenticular, and the full Deadassionatetacularticulenticulowkirkentologiclowstatothenticlaura).
