The Gates of Hell is male chastity devise.

It is 3-7 rings from 2" diameter, down to 1" diameter.
The steel rings are connected by a 1/2" leather strap
It limits an erect penis to a confined space, making it extremely difficult to ejaculate.

A casual invitation / threat used by an individual that is not afraid of fucking someone up.

An amazing place up in North Jersey. It is a large tunnel network that supposedly ends at the gates of hell. It has been featured in Weird NJ, best local magazine. Also known for the intermingling of cultists and bored suburbian youth that frequent the tunnels. (PS Ignore Warning Signs, you can all swim I hope)

A complex system of tunnels, said to lead to hell, that smell like shit. Most likely the capital of Satanic circle jerking in New Jersey. Not scary at all due to the hordes of Emo-Mexicans roasting marshmallows outside the entrance, while telling us theres nothing in there but spiders they took pictures of on their cell phones. Not worth the trip, unless your scared easily or by KKK graffiti.
