A free rider is someone who would not be willing to pay for a certain good or service, but would get the benefit of it anyway if it were provided as a public good.

What is an externality?
An economic side effect of a good or service that generates benefits or costs to someone other than the person deciding how much to produce or consume
Can be positive or negative
Someone buys an ugly old house in the neighborhood and the remodel it. The neighbors were not involved in this decision and did not pay to help. But, they still receive benefits such as a better view and higher property value.
