I dont know if many are gonna know what I'm talking about, but surely someone has to. So where I'm from, theres like this "trick" on measuring your size without having to dig into your groin by measuring the length between the tip of your middle finger and the base of your hand. And I was just curious if any experts out there knew if this was actually any good or a bunch of bullshit like most things of this nature are lmao.
