A Sneaky Finger is a life or death situation where the victim/friend/stranger has to have a a finger inserted into them for safety.
The only acceptable time to sneak a finger into a friend/stranger/victim is when they have gone a bit limp (possibly due to large quantities of CBD / THC / AlCOHOL Consumption
but their flatulence is horrendous and their breathing is weak.

Therefore having no cork to hand a finger is the right tool in this emergency
to ensure their safety breathing wise, as their gasses re enter the lungs directionally upward.

Additionally it has been established that there is a difference between consent (to the right) and rape (to the left.) It's Sneaky (in the middle) as it is neither consensual or not , but necessary in this application.
