rule of thumb

one of the most commonly misconstrued sayings, an example used in Boondock Saints "a man is allowed to beat his wife with a stick no thicker than his thumb." A claim made by a satirical caricaturist by the name of James Gillray against a judge. The first and original use of the saying is as simple as the words. The thumb was used as a readily available tool of measuring. Such as the Tailor's rule of thumb "the circumference of the thumb twice, is the circumference of the wrist, twice the circumference of the wrist is the circumference of the neck, and then twice the circumference of the neck is the waist's circumference." Then there is the Brewer's rule of thumb where if the temperature of the wort wasn't insufferable by the thumb it was cool enough to pitch the yeast. It has now been used as a term of commonplace knowledge in a field.

Rule of Thumb

During coitus, if you're ready to move from the pink to the stink, but you're not sure if she's into it, you can always gently mash your strongest thumb into her butthole, as if to say, "What do you think?" If she smiles or goes with it, trade your thumb for your cock Indiana Jones style.

SHORT ROUND: Dr. Jones, is that your thumb!
DR JONES: No... not anymore according to the rule of thumb.

Rule of thumb? Can't do too much damage with that thing, can we? Perhaps it should have been the Rule of Wrist. - The Boondock Saints

Rule of Thumb

The rule that basically a lot of modern women will allow a man to sneak a finger up their ass during sex, but will draw the line at full anal sex. The rule of thumb states that a thumb, being thicker than the average finger, inserted into a female's ass consensually will ultimately then mean that the consenting female will allow said male to insert his penis into her ass.

Davy and Stuart were together last night, do you know what happened? No, but apparently she failed the rule of thumb.

Davy said he's meeting Stuart tonight and won't try anything until he's found out whether Stuart passes the rule of thumb.

Rules of Thumb

The three simple rules Valves' art staff used for creating the box art of the game Left4Dead.

The Rules of Thumb are:

1) There should be a hand in it somehow

2) The hand should have a thumb bitten off, so customers would look at the four fingers remaining on the hand and think, "Hey, four."

3) Under no circumstances would they use Photoshop. L4D is a visceral experience, and its box art deserved the same approach.
