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.
