Truck-kun
The self-aware isekai meme: the truck that kills the protagonist so the story can transport them.
Truck-kun is the affectionate name for the isekai genre's most common inciting incident: the protagonist is hit by a truck and wakes up in another world. The "-kun" honorific is the joke; the community uses the meme self-awarely, celebrating and mourning the genre's most industrious character, the truck itself.
Its craft significance is honest signaling: a truck opening tells the reader exactly which contract they are signing in the first page. Like all memes it is also a saturated one; the genre's own documentation treats the transportation event as obligatory but its vehicle as optional.
