Primarily, Japanese anime that relys heavily on showcasing mecha: robots/spaceship/fighterplanes/war machinery-heavy action. Particularly when they are engaged in violent combat and especially if the mecha are transformable.

There is no sexuality or actual 'p0rn' as the focusunless it is a doujinshi or hentai fan svc. storyline. The visually riveting & gratuitous element is the visceral & bloody nature of such combat and the war-romance of glamorized, high tech machines destroying each other; as visually addictive to tech-nerds as actual sexual content eg:

Massive exchanges of ordnance and stunning dogfight/combat maneuvers against cityscapes, alien environments or amidst massed fleets of capital ships and blossoming,null-'G'explosions; detailed, 'motion-physics' accurate and almost photo-realistic depictions of soldiers/pilots decompressing in hard vacuum, being eviscerated or burned alive; depictions of ordnance impacts and nuclear explosions, incl. progressive flash/blast/heat, that have otherwise only been captured with motion picture cameras using strobes, frame progression and other photography tricks.

Can apply to non-Japanese, SF motion pictures replete w/the aforementioned.

A very large, ribbed metal penis. It isn't attached to a person but yet has a mind of its own. It enjoys penetration of all sorts.

Giant robot. Refers to humanoid types seen mostly in animé (Japanese cartoons) and Japanese games (i.e. Armored Core). Mechs/mecha can be anywhere from 30 to a few hundred feet tall and are usually pioleted by people. They can be used for many things, like constuction for example, but more often warfare.

a mechanically enhanced cow used to infiltrate enemy territory undetected, usually deployed in herds.
The only way to get past the enemy defenses was to strategically place a herd of mecha cows who could stroll in easily unsuspected, much like the Trojan horse of old.
