The image shows a first-person view of someone's arm extended forward holding a can, from which a stream of a white substance is being sprayed towards a child standing by the roadside. The child appears to be nonchalantly walking with a mildly surprised look on their face as they are being sprayed. The scene takes place on what looks like a suburban street with houses and leafless trees in the background, suggesting it might be during a cooler season.
The text overlaid on the image reads, "When I see the person who Blue Thumbed my meme." This suggests a humorous or exaggerated reaction to someone who has presumably given a negative rating (indicated by "Blue Thumbed") to the meme creator's content on a social media platform. The phrase "Blue Thumbed" likely refers to a 'thumbs down' or a 'dislike' action on a social media platform where such an action is highlighted in blue, which is a typical color used for various interactive elements on several popular platforms.
The humor arises from the evident absurdity and hyperbole of the depicted reaction. In a literal sense, the image shows someone taking a vengeful action (spraying the child) for a trivial online interaction (disliking a meme). It is understood that such a response would be highly inappropriate and disproportionate in real life, hence, the contrast between the depicted action and an appropriate behavior creates the humor.
The choice of spraying the child also adds a visual slapstick element to the humor. Slapstick comedy often involves exaggerated physical actions that are improbable in real life and invokes laughter through shock, surprise, and the relief of knowing it's a fictional scenario. The white stream directed at the child echoes the antics seen in slapstick sketches where characters get hit with pies or squirted with various substances.
The facial expression of the child plays a role in the comedic effect as well. The child's relatively calm demeanor in the face of being sprayed gives an incongruent reaction to the action, which can heighten the comedic value of the image. This suggests a nonchalant attitude towards the absurdity of the situation, which is often an element used in humor to amplify the ridiculousness of the scenario.
Lastly, people might find the meme funny because it dramatizes a daily occurrence in the digital age – the emotional investment and reactions people have towards the approval or disapproval of their content on social media. The meme uses exaggeration to poke fun at the sometimes disproportionate importance placed on social media interactions, making light of the fact that while online engagements can feel impactful, the depicted response is hilariously excessive.
