The term "lofi" in a porn video context refers to "low-fi," which stands for low fidelity. This tag suggests that the video features a more amateur, raw, and unpolished aesthetic or style. It could include elements such as grainy footage, less professional lighting and sound quality, or unconventional camera angles. The tag might be used to denote a certain level of authenticity, spontaneity, or intimacy in the content, often appealing to viewers who enjoy more candid or realistic portrayals of sexual encounters.
