Just as pretty much every evangelical church has a Youth Group Guy, pretty much every evangelical church also has a Pervy Church Geezer.
On the surface, the Pervy Church Geezer looks like any other typical Church Geezer**. (**Roughly age 55+, but the whiter/less hair, the more geezery. “Old enough to have a grandkid whose mom wasn’t a teenager” is another good off-hand measure.) Like most Church Geezers, Pervy Church Geezers tend to be longtime church members in good standing, with faithful, post-menopausal wives and adult children who have permanently left the nest. The main difference is that respectable Church Geezers actively refuse to be attracted to young women, reminding themselves that (a) young single women at church could (theoretically) be their daughters or granddaughters, and (b) their wives deserve their libidinal respect, while Pervy Church Geezers treat Sunday morning greeting time as a three-minute Mardi Gras: a time when all of the normal rules of conduct don’t apply, and they get to hug and squeeze young women without prejudice under the guise of church family friendliness.
For the typical Pervy Church Geezer, this short greeting window is the highlight of his week, as it is most likely the only time he (a) sees any young women, and (b) is permitted physical contact with them. If you are a young woman and you get to know a Pervy Church Geezer, he will probably keep tabs on your attendance and mention to you that he missed you if you skip a week. He may also compliment you profusely on your appearance, especially if you wear a dress. And if you wear heels, his head may explode.
One thing that Pervy Church Geezers are not is creepy. Creepy church geezers are sexually threatening; Pervy Church Geezers are not. Rather, Pervy Church Geezers are like jolly grandpas getting one last jump on a car battery.
Although I will say from experience that if a Pervy Church Geezer sticks his face in your neck when you give him his Sunday morning hug, that might be crossing the line a little.
