The skin on the back of one's elbow is called olecranal skin, or colloquially, a weenis.

He describes it as almost traveling back in time.
Do blood? Really? Travel away from the heart? Looks like we have a conundrum boys - if blood travels away from the heart and through your body - How does it get back to your heart? Is it really traveling away?
Veins are provided with "one-way" valves along their route back to the heart. I used to notice that the veins on my forearm inflated and bulged when if I swept my fingers down from my inner-arm elbow to my wrist when I was young and skinny. This clever arrangement results in the reduction of effort on the heart to pump blood during muscular exercise.
"Out and back" in the context of a round trip journey means traveling to a destination and then returning along the same route. It refers to a journey where the same path is taken both to and from the destination.

It is called a wenis.
Because your elbow is made up of a compact bone or funny bone that releases more pressure than your back since it has a spinal cord.
The antecubitus is the area distal to the humerus, proximal to the radius and ulna, and anterior to the trochlea. Layman's terms - face of the arm opposite the elbow, or the inside of the elbow.
The bony point of the ulna that forms the elbow is called the olecranon process. It serves as the bony prominence at the back of the elbow joint and provides attachment for various muscles and ligaments that help in elbow movement and stability.
