There is a 2d universe.
This 2d universe it infinite, the coordinates of it being described as (∞, ∞) going down-up, right-left infinitely.
But wait! Someone in it described a new concept known as "multiverses"
To scale his character in 2d, he starts saying that his fictional verse has INFINITE 2d universes that are INFINITE stacked upon each other in front-back coordinates as a multiverse.
Making the coordinate space of his suggverse character (which he can totally blow up btw) described in (∞,∞,∞)
People think this kuh-razy nonsense.
Nobody can even mentally grasp or visualize how this set of multiverses exist.
How would these universes even occupy the same space as eachother?
How are they separated from one another?
They all call him a fag.
It's inconceivable.
You, a 3d person, are watching this laughing, because all that guy achieved in the end was describe the universe you are currently living in.
