What drives me nuts is when some of the newer-to-quilting bloggers refer to the process of stitching the layers together (properly termed "quilting" in my mind, as well as historically) as "topstitching".
Topstitching is a real term. It's what you do on jeans. It's often used in bag and tote construction. It's done on upholstery. But it's really very different from the skill set that is correctly known as quilting (be it hand or machine, domestic or longarm).
But -- I think they use the term topstitching because it's confusing to refer to quilting as both the stitching technique, and the overall hobby. So they are trying to distinguish between the piecing / patchworking portion of the work, and the quilting.
Still -- it annoys.
