Rule of thumb

An approximate way of doing something based on presumptions rather than fact. Contrary to popular belief, the idea the law once allowed a husband to beat his wife as long as the device was no thicker than his thumb is false, as such assaults were outlawed for centuries in common law, although the ban wasn't generally codified in written law until the 1980s.
A driver kept going 5 mph over the speed limit, thinking the police had a rule of thumb that it was a waste of time to give out a ticket to anyone going anything lower than that.

Three Giggle Rule

3 giggles make em jiggle

A theory that outlines a strategy to attract females for mating. If you can make a woman giggle, (not a laugh, it has to be the cute kind of shit that girls do. You know what I mean) three times in one sitting, then you have a high chance of experiencing sexual encounters with her
“Remember that girl from the party last night that thought I was so funny? We banged.”
“Damn really, it was that easy?”
Yeah bro, three giggle rule. After the first two I knew it was a wrap.”

To take the first parking space one runs across in a lot, instead of circling to find the closest one to an entrance. First uttered in 1991
Man screw this I’m not a fat fuck, I’m invoking The Lee Rule. We can save 5 minutes, by walking an extra 50 feet to get inside the store.
