This is the name of a sexual position which is both very stimulating for both the male and female. You enter from behind as you would in "doggy style" but then, the female lies on her belly with her legs together. You lie on top and continue to thrust as normal.

It is named the accidental because you know whoever invented it did so because himself and the female fell over doing doggy.
"Lets do doggy"
"ok"
(both fall over)
"ooooooooh, awesome!!!"

(doin doggy)
"the accidental???"
"hells yeah!!!"
"boom boom!"

Verb:

To make mistakes in a sentence such that the sentence is impossible to comprehend. Usually when a verb, adjective, noun or pronoun is misplaced or missing. Failing to put a period can lead to an accidentally (components of one sentence can be confused to be in another. Thus misplaced components).

Usually used by the person responding to the sentence as a form of irony (since accidentally is an adjective, so using it as a verb would mean it is misplaced).

Using an accidentally is an accidentally.
Example 1: Missing pronoun

Person 1: I cant believe not coming.

Person 2: What? I think you accidentally your post.

Example 2: Missing period {2 options}

Person 1: She was running {period} until 5pm {period} I was watching TV

Person 2: What? I think you are missing a period. You accidentally there.
