Gigerotic is a merge of multiple LoRAs I made several months ago. I don't remember what LoRAs were used aside from this older Giger LoRA. I do remember I made it because that Giger LoRA didn't trigger well for anime and also didn't do nsfw well. At full strength it will completely overpower your image, so it's best used from .4-.8
It doesn't exactly have trigger words - but it does need something to work with. Industrial style settings work best.
You can use at low strength in 'normal' images and it can produce a nice contrast boost.
