"Gum up" is an expression that means to cause something to become stuck or not work properly. It is commonly used when referring to mechanical or electronic systems that can become clogged or jammed. For example, if too much paper is inserted into a printer, it may gum up and stop working until the excess is removed. The expression can also be used in a broader sense to describe a situation in which something has become complicated or difficult to manage.
