when someone pulls out a gun on the elevator
When you're outside or near an open window
In the spa/jacuzzi ;D
When you're in bed. Pull the covers over her head and marinate in it together. It's a bonding experience, she'll love it.
Its very classy
when it's really loud in the car and you're driving past a sulfur refinery xD
right after you brakeup.
Whenever you need to fart...but if you are in a closed space, open a window :P haha
It's fine as long as you don't fart like the walking farts and if you get up and leave the room so I don't have to smell A.S.S for a good ten minutes. That's what I always tell mine. I even follow the same rules.
