2. a Pinterest pin of great and often frightening size, force, or complexity. Pinterest may be more pinstrosity than not - a high percentage anyway. Recipes, sewing, crafting, home decorating, DIY projects - all are subject to posts from the experienced who overestimate the same skills in their followers.
