Origin of the Name

Sean got his name "Jack" from his mother and subsequently friend, who gave him the nickname when he was young, as "Jack" is a common nickname for the name "Sean" in Ireland. His friends started calling him "Jacksepticeye" after he got cut in the eye by his friend's glasses in an accident that happened when he was playing football. According to him, the wound bled for quite some time and became infected after a few weeks, hence the name "Jacksepticeye".
