>>33761905Teflon is a material used in cooking pans, specifically because they cook well and also avoid any residue sticking to them.
This term has been adapted to famous people ranging from celebrities and politicians that are so favored by the public and their specific fans that no matter what kind of dirt was thrown at them, nothing "stuck" to them, similar to Teflon.
It's also why Trump has been routinely referred to as Teflon Don, even before his run for public office.
