The Blank Stare is usually performed by one character in response to another's actions or verbal tirade, either in mind-numbing disbelief or disappointing awe, and especially when the latter character happens to go off the rails or otherwise show an aspect of themselves wildly different from what was expected.
It is usually performed primarily in a visual medium such as film, television, or graphic novels, and is done for both humorous and dramatic effect; the dramatic type tends to display the moment when you can no longer depend on that particular character anymore, while the comedic one usually reveals a WTF-type scenario similar to a Double Take or a Spit Take. The verbal version of this, which usually accompanies one of these, is the Flat "What". Compare Thousand-Yard Stare, which is similar, but is meant to showcase the extreme trauma the stare-giver has gone through.
- Abraxas (Hrodvitnon): Vivienne Graham, during her reunion with Madison Russell following Vivienne's transformation into Monster X, playfully gives Madison an unimpressed blank look when the latter teasingly asks Vivienne to perform a dance with her new Titan body.
- In a comedic non-canon post on the author's Tumblr, Maia Simmons and the twins Don and Meg can only stare blankly when Walter Simmons, in a clear potshot by the author at Elon Musk, decides to rename the latter two of his "children" as Æ-Exa Dark 12 and Sidereal Exxon-99. Try working out how to pronounce that in under 30 seconds.
- One of the most notable moments in The Beatles' film Let It Be is a scene in which Paul McCartney gives John Lennon an earnest talk about how the band is getting stale and, to liven things up again, they need to get on the road and play live shows. John, who had no interest in this idea, simply stares at Paul blankly.
- Thor: Ragnarok: Loki appears as an illusion in the dungeons the evening before the Gladiator fight and talks to Thor how he couldn't help him in front of the Grandmaster but has plans about getting rid of the Grandmaster so that he and Thor can take over Sakaar, and advises Thor to forget about Asgard because they don't stand a chance against Hela. Thor just throws rocks through Loki's illusion, not answering him, and when he runs out of rocks he just stares into space, still angry at Loki for having faked his death four years ago, and blaming him for their father's death.
- The Peripheral (2022): Wilf develops a spectacular one after he visits Lev at his gentlemen's club to tell the oligarch that his family has been killed in Flynne's stub... Only for Lev to laugh at him, explain that he arranged the murders himself because his other self's presence made him uneasy, and elaborate on his plans to open other stubs and exploit their inhabitants for money, leaving Wilf to goggle in horror at the abject Lack of Empathy.
- Supernatural: The looks on the other witches' faces when Rowena proposes they call themselves the "Mega Coven" in "The Bad Seed".
- While promoting The Marshall Mathers LP 2, Eminem was doing a persona where he'd spend his TV appearances gawking vacantly at the camera with his eyes blinking slightly out of sync - a sort of parody of Ad-Rock, whose music inspired a lot of the content on the album. Most viewers just reacted with concern for his mental health.
- During the first season of The Muppet Show, Timmy Monster was depicted with this.
- In Sneaky Goblins, Bog pulls one of these when Dank unthinkingly admits to having lied to him earlier.
- Phoebe momentarily gives two in Chapter 2 of Star Impact; once after Aster revealed herself to be the new bearer of the Shooting Star gloves, and again later when Stryker requested her to spar with Aster, which quickly gave way to a Big "WHAT?!". The latter page's Alt Text unabashedly lampshades it:
"Blank-faced Phoebe has a high cuteness stat."
