Grammatically, the term functions as a noun phrase. The core element, or head noun, is "guy." This noun is modified by the adjective "Chinese" and the proper noun "Patriots Day," which acts as a noun adjunct to specify the context (the 2016 film). The entire phrase serves to identify a specific individual.
The phrase refers to the character of Dun Meng, portrayed by actor Jimmy O. Yang in the film Patriots Day. Dun Meng is the real-life entrepreneur who was carjacked by the terrorists Tamerlan and Dzhokhar Tsarnaev during their escape attempt following the Boston Marathon bombing. His courageous escape from the vehicle at a gas station and his subsequent call to the police were critical turning points in the manhunt. The information he provided allowed law enforcement to track the stolen SUV's GPS, leading them directly to the perpetrators in Watertown, Massachusetts.
This search term illustrates a common method of audience recall, where a character is identified by their notable attributes (ethnicity) and the media context (the film's title) rather than by their name. The popularity of the query underscores the memorable and pivotal role Dun Meng's character and real-life actions played in the narrative of the Boston Marathon bombing investigation.
