Best Barometer 

This is a synonym for a penis in porn films. It is derived from the ability of an experienced penis and its experienced user to determine the suitability of a vagina, breast, anus or in fact any other body part for fucking or coital relations.

Typically the barometer functions by being slapped or thrust vigorously through or against the body part under test.

"My penis is the best barometer. The best test of a good tit!"

Bombay barometer 

That miraculous sensor situated in the anal tract that enables the operator to determine whether the chamber is loaded with gas or solid matter, before risking a fart. The Bombay barometer may give faulty readings when, for example, swamped by large quantities of beer and curry, with disastrous results.

"Who dropped the dark blockbuster? Smells like someone's Bombay barometer failed!"
