No. The action of rubbing together two Doritos chips would crumble them before sufficient friction could result in enough heat to cause combustion.

Examples of two objects that rub together include rubbing a balloon against fabric to create static electricity or rubbing two sticks together to start a fire.
By rubbing 2 objects together. Like your hands. They start to get hot.

Rubbing two sticks together will generate heat to start a fire.
You can start a fire by getting two sticks that are somewhat long and rub them together until smoke comes. Then start blowing gently and a fire will start.
Rubbing two sticks together creates friction, which generates heat that can ignite the wood. Metals are better conductors of heat, so when two metal pieces rub together, the heat generated is quickly dissipated, making it difficult to generate enough heat to start a fire.
The energy produced by a scout rubbing sticks together to start a fire is primarily mechanical energy, which is converted into thermal energy (heat) through friction. As the sticks are rubbed together, the heat generated can ignite the combustible material nearby, resulting in a fire. This process exemplifies the conversion of mechanical work into thermal energy.
Using a fire starter such as matches, a lighter, or flint and steel is a more reliable and efficient way to start a fire than rubbing two sticks together. You can also use kindling or fire starter cubes to help ignite the fire more easily.
Fire by friction!
