upchucking

Upchucking is the present participle of the informal verb upchuck, meaning to vomit. It can be used intransitively, as in “The child was upchucking in the bathroom,” or transitively, as in “He upchucked his dinner into the sink.” The expression is blunt and sometimes sounds comic or euphemistic, but it names an unpleasant bodily function without the clinical neutrality of “vomiting.” Because the verb can be used with or without an object, upchucking may refer to the process itself or to the act of expelling a particular substance. It is best suited to informal narrative, dialogue, and similarly frank contexts; formal medical or educational prose usually prefers “vomiting,” “emesis,” or “regurgitation,” depending on the particular medical meaning. Although the tone may occasionally be humorous, the word is not a euphemism for merely spitting saliva: vomiting normally involves the stomach, whereas spitting does not. The compound’s transparent formation—up plus chuck, “throw” or “eject”—helps explain both its vividness and its long-standing use.

To vomit; expel the contents of the stomach through the mouth. The verb may be used intransitively or with the expelled material as its object.

Etymology of upchucking

Upchucking comes from the verb upchuck, a compound formed in the early 19th century from up and chuck. Chuck was used for throwing or ejecting, and the compound came to mean vomiting or throwing up the contents of the stomach. The deeper ancestry of chuck is uncertain, so a more specific Latin or Germanic derivation should not be assumed.
