The phrase "riffsandskulls" does not appear to be a direct porn video tag. However, it seems to consist of two parts: "riffs" and "skulls."
1. Riffs: In the context of porn videos, "riffs" could refer to various sexual acts or positions that are performed in the video. For example, "doggy style" is a riff, as well as "reverse cowgirl." It might be a slang term used by the uploader or community to describe a specific scene.
2. Skulls: This could potentially refer to hardcore pornographic content involving skulls in a sexual manner. This might involve BDSM practices like bondage or roleplaying, where skull-related props are used for visual impact. It could also mean that the video features intense and aggressive sex, metaphorically referred to as "skull-fucking."
Since there is no direct English translation of the phrase itself, we can only make educated guesses based on the individual words within it. The intended meaning may be completely different if another language was used or if it's a unique slang t
