You can add another slut tell to the patented and first-of-its-kind Chateau Heartiste list of slut tells.
Commenter backchecking explains,
In my experience, gals are extremely aware of ring etiquette. A ring finger is raised like garlic to a vampire — or flashed to evidence availability. This tic comes largely from the subconscious.
In a similar vein, lots of cheap rings and bangles indicate a babe on the hunt. Only one finger will be flamingly naked.
The “ring finger glaring omission” slut tell is almost as reliable as the tramp stamp. A girl with multiple rings on multiple fingers except the one finger that advertises monogamous commitment is practically sending up a Snapper Signal to the city’s gine fighters. Dark knights will converge on that girl to give her the hero sandwich she needs, even if it’s not the hero sandwich she deserves.
Bonus slut tell!
If a girlfriend or wife suddenly requests that you wear a condom, she’s a slut… with another man. No doubt she’ll offer some lame excuse for the change in pound town policy, but don’t believe her. The “abrupt condom policy change” slut tell is evidence that a woman wants to block your seed to allow unobstructed passage of another man’s seed. If you are the other man, and a woman has suddenly permitted you raw god* rights of entry, practice due calendar diligence. Every player should become acquainted with his LTR’s ovulation cycle.
*Ed: This was originally supposed to read “raw dog rights of entry”, but I like the typo better.
