Hell is, according to the Christian faith, the place evil people go when they die (or sometimes visit when near death). It is run by the Devil, and is the traditional Christian representation; all fire and brimstone.
The Devil enjoys dealing out cruel and ironic punishments to the denizens of Hell. Homer was fed all the donuts in the world by the Blue Demon, but didn't take this as a punishment, demanding more donuts. Hell had a poorly-managed barbecue; this succeeded in breaking Homer's spirit.
Bart had an out-of-body experience which took him there briefly before coming back to life after he had been hit by a car. While there, the devil revealed to him that he was not supposed to die until the Yankees won the pennant.
Professor Frink once tells the Simpsons family "I have just discovered that Hell is real, and everyone goes there".
