Earfucking is the practice by a persons of talking non- stop. If anyone else tries to comment the earfucker simply talks over them. The earfucker is a nightmare for people who are trapped with them in a car, a dinner table or office. They are often also called time suckers or a time suck.

He is always in non stop talking mode. He earfucked me at my desk for a full hour. He's a total time suck.
