The birther movement gained attention during the 2008 presidential election.
Birther → It is formed from "birth" (from Old English "byrþ", meaning the act of being born) and "-er" (meaning a person who). A birther is a person who is associated with or claims to have given birth, or in some contexts, refers to someone who promotes a specific belief about the circumstances of a person's birth.
Think of 'birth' as the act of being born, and remember that a 'birther' is someone connected to that act, often in a specific context.
