Infodumping is the action of supplying a large amount of information at once.
The term was first used in 1978 in the Proceedings of the Southeastcon Region 3 Conference 353.
[1] Over time, the term was adopted in the context of literature (particularly within science fiction[2]) as well as by the autistic community.
[3] In the latter, "infodumping" is understood as one element of autistic expression, particularly as it relates to their topics of interest.
[4][5][6] Infodumping is also associated with attention-deficit hyperactivity disorder.
