Tangent

Sine, cosine, tangent. Alternatively, cosecant, secant, cotangent are the reciprocal identities.

In any flame war, argument or discussion online, it is important to have an entirely irrelevant tangent. This enables the thread to be completely derailed, allowing for unexpected drama and lulz. Tangential discussions are very popular with trolls who find it amusing to destroy any possibility of a conversation making any progress towards reaching a satisfying conclusion.

It has been hypothesized that the creation of tangential discussions of continuously decreasing relevance can indefinitely circumnavigate Godwin's Law. It seems doubtful that this hypothesis can ever be tested as no troll is likely to have sufficient expressive ability to avoid the effect of Protagoras's Law throughout a thread of infinite length. Nonetheless, you are welcome to refer to this concept as Banbot's Hypothesis.
