The symbol beneath the equals sign

[spaghetti3451]

What does the symbol \underbrace{=}_{\wedge} mean?

P.S. : The symbol beneath the equals sign is meant to be a triangle.

i.e. a triangle beneath an equals sign.

I don't recall ever seeing that. What was the context in which this appeared?

It's an agry face with a ridged forehead, bushy eyebrows(so big, they cover the eyes), and an angular frown.

Hi Failexam, show an example of the context where the symbols is used.

An equals sign with the triangle on top is often used to mean "equals by definition", but I've never seen it shown with the triangle below.
