Homer Simpson is the central father figure in The Simpsons, the long running animated sitcom created by Matt Groening that first aired in 1989 and is voiced by Dan Castellaneta. Clips of Homer reacting, shrugging and admitting confusion have circulated for years as reaction audio on soundboards and in edited videos. This short line became popular because Homer is widely associated with well meaning cluelessness, so a brief admission from him works as shorthand online whenever someone wants to show they have no idea without explaining further.
