The release of hot stink from the anus witch may cause some ring sting, the feeling of acid eating the inner lining of your shitta followed by the relaxing sensation of relief.
"I need to do a hot fart"
"aww that was a ring stinger but wat a relief, i think i need to do a runny hot shit"
"go squirt one out then"
"it feels like hell wants to come outta my ass hole, after this i'm gonna need to have a shower to wash the shitty acid outta my ring hole"
