A pothole to make it clear that a statement is honest and genuine, although it's in a context that could have it easily mistaken for an insincere comment or joke. Say someone gives a suggestion, and people respond with "I think it's a great idea!". Since that comment can be both genuine and insincere, this is a tool to help people know you are being genuine.

The reason for this can largely be seen in PoesLaw. Some people actually don't know if others are being sincere or not a lot of the time, especially where text isn't as emotive as necessary to convey the sincerity properly.

Please do not pothole to this page {{iron|y}}ically. That would be super confusing.

In some instances, this can even be a trope in a work, when a character is usually sarcastic or snarky, but then they get moments where they mean what they say.

In ProfessionalWrestling, this is often known as "shooting".

Contrast SarcasmMode (where you don't really mean it), HumorMode (when you're just kidding around), and SchmuckBait (where traps are worded as sincere warnings against falling into them).
