This refers to the metal button that is typically screwed into the body of an acoustic or electric guitar onto which the strap is attached during live performance where the player must be (or chooses to be) standing. There will be two strap buttons on a guitar, one for each end of the strap. Placement of the forward button on an electric may be on the body (as in a Gibson Les Paul) or top horn or bout cutaway (as on a Fender Stratocaster). The rear strap button is almost always positioned at the mid-point of the end of the body, behind the bridge. On some non-classical nylon-string guitars, the strap button is a peg made of wood or plastic that is removable.
