Remora is a noun that refers to a hindrance or a drag.

Our word of the day gets its name from a long, thin fish that is known to attach itself to an animal and behave like a parasite. When used outside of the realm of the animal kingdom, it may refer to anything that acts in a parasitic manner, for example: Those reporters really can make it difficult for the police to do their jobs. They attach on to us like remora and not let go until they get the story they want.
