I can make a loud click sound with my tongue. Most people can click their tongue and it sounds rather small and kinda wet, and it’s often a double click because the tongue hits the bottom of the mouth. When I do it, I can stop my tongue from hitting the bottom of my mouth, and it makes a very loud “knock” sound, like someone knocked hard on a wooden door.

It hasn’t been very useful in my professional life, but it has been extremely amusing using it to scare people. Or compete with my dad to see who can make the loudest click 😂
