Missing, extremely new, or very obvious to obtain.

This achievement has no cultural references in the English and Chinese versions. It is likely specific to the game. The player helps Fedora win the bet against Pela by becoming the champion of the Aetherium Wars tournament, implying that Pela bet against the Trailblazer. As such, the achievement name is a jab at Pela for betting on someone else.
