Arm-Bridge

When the arm of a relative giantess is used by a relatively tiny being as a kind of bridge, which can be carried from hand to shoulder or vice versa.

Normally, the arm should be almost parallel to the ground, but in fiction ground characters are shown with a "magnetic" ability that allows them to walk or run along the arm without falling, even when the arm is almost perpendicular to the ground.
