1. adv. indicating extreme urgency to respond to an immediate need that the speaker has most often been recently made aware of, although it may also refer to a need that, while the speaker has had a prolonged cognizance of, the relief of which would require the briefest of intervention by another party or minimal rectification by an object (i.e. a urinal). A portmanteau of ' yesterday' and 'now' with the component , 'yesterday,' referencing its colloquial usage as an adverb to indicate urgency to resolve a prolonged process; and 'now' to transmute the adverbial to impart a more immediate, impulsive need.
