That part of the exhaust manifold system, on older vehicles, known as the heat riser and necessary to aid in fuel evaporation and make the transition from cold to hot idle engine operation efficiently.
The first cold day I cranked the old buggy over it was obvious the frabulator valve was rusted and frozen up as she wouldn't run right and carb touch-up adjustments made no difference.

When a man has just pulled up to a urinal in a public restroom and has a gas bubble drop to the back gate at the same time as the flow is about to start. At this moment, a friend walks in and calls you out by name. Now your identity is revealed to others that are in the stalls. With this happening, you can no longer let the brown cloud come flapping out. The only thing you can do is limit the flow with enough squeeze on the urethra that didn’ doesn’t compromise the rectum seal.
Fuck man, my boss walked in to bathroom right when I pulled up to the urinal. A gas bubble dropped and I was working the valves to save myself from an embarrassing fart.

If Jimbo tries to pull that crap again he'll receive a good swift kick in the Sally valve.
Kirsty is a filthy bitch, she'll do everything, including taking it in the Sally valve.

The blamed single-point failure of a man's proposed mission to get laid when the real mission was to Premature Ejaculate and cock block his own cock, thereby wetting pussies but never giving them the satisfaction they don't deserve.
This has been said to be the highest zen move of a few super advanced fuck masters. Namely the Oyel Giants.

Whatever, I've been fucking around with Joe since Billy's shuttle valve is acting nuts and he leaves the seat up and my butt keeps hitting the toilet water and whatever I'm just like fuck that, I'm not even going to tell him, but then again Joe's shuttle valve has been acting weird too lately. Whatever I deserve it... I'm a bitch
