The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
If the outsider is not human and is fascinated and confused by normal human objects, it may also be Xenofiction and Humans Through Alien Eyes.
Edited by KDMundane Object Amazement is also kind of related.
Mundane Made Awesome if Bob dialing his phone to ask Alice on a date is treated with all the tension of diffusing a bomb.
Humans Are Cthulhu for something like a squirrel's perspective on a human campsite; often overlaps with the previously mentioned Humans Through Alien Eyes when the aliens are sufficiently different in biology and/or psychology. note
Bonus trope: Shallow Parody for the second one- the stilted mix of Description Porn, Melodrama, and Beige and Purple Prose is actually channeling the standard Pulp Magazine vibe, regardless of genre. (See also IKEA Erotica and Description in the Mirror for a couple specific forms common in both Romance and Detective pulp, for instance.)
Edited by Scorpion451Wildlife Commentary Spoof is essentially based on this type of humour.
A type of humor that involves describing everyday objects and activities from the perspective of a fascinated, often confused outsider. Like "Body Ritual Among the Nacirema" or "If All Stories Were Written Like Science Fiction Stories."
