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.

Get the Rule of thumbmug. The teenage act of using your thumb as a hole guide for your cock which is larger than she is used to. After slapping your fumbling dick in your palm, you gently insert your thumb into her pussy. Like Houdini you simply run your cock along your thumb, using it like a ruler or a guide, to direct and allow an easy and simple access’s to an otherwise unsatisfied pussy.
She was too tight for me, it was dark and I couldn’t even find her hole

Man taught him. After a while the crafty fucker worked his huge knob to the hilt - and we didn’t see him for 3 days!
