Flerfspective is a term for the butchered mess that flerfs make out of linear perspective when using it to explain:

Flerfs that realise the painfully obvious flaws with using flerfspective to explain the above phenomena will sometimes resort to flerfraction.

Vanishing Point Issue

A key misunderstanding is that flerfs think the vanishing point lies at a finite distance from the observer, when it's actually infinite.

The elevation angle of Rowbotham's sun would decrease as it moves away horizontally, but an elevation of 0° is the infinitesimal limit of this series.

In other words: the sun could recede horizontally forever, but could still never actually reach 0° elevation.

Without this limit, a flat and level floor beneath an observer would be able to block his line of sight to an object that's above him, which is patently absurd.

Side-by-side time lapses: left is a vanishing point demonstration, right is the actual sun. The sun does not set by “moving away”

Rhetoric

Despite extravagant, ongoing efforts among globers to explain the above issue, to date apparently no flerf has ever comprehended it (except ex-flerfs).

When confronted on it, flerfs generally become chaos gremlins and rebut with statements like:

For this reason, the "flerfspective" concept is a rich source of word salad.
