This porn video tag is a combination of two phrases: "Gaya Patal" and "Anal".
"Gaya Patal" refers to the 16th and lowest part of the 18 levels of Naraka (Hell) in Hinduism, Buddhism, and Jainism. It is known as the worst level of hell, where extremely evil and sinful souls suffer unimaginable torment.
In this context, the term "Gaya Patal" is likely used as a metaphor for intense sexual pleasure or kinky fetishes, since the original meaning is related to extreme suffering and punishments. Therefore, a video with this tag may involve intense, anal sex scenes that are considered taboo or extreme by some viewers.
The word "Anal" refers to the anus, which is a common focus of sexual activity in porn videos. It indicates that the content will likely feature anal penetration, either through oral sex, fingering, or penetrative sex with a penis or toy.
