"Fan-out" means how many inputs can be connected to an output.  For example, typical TTL devices have a fan-out of 20, so you can theoretically connect up to 20 inputs to a single output and still have sufficient voltage and current for the circuit to work.  Typically, however, if you try to push this limit you run into other physical problems like capacitive loading and noise caused by long PC board traces.
