A voracious pussy-licker can sometimes make a butt-related accident, hence, assident:
When you're eating a fantastic snizz and your tongue slips in her asshole. Perhaps the word is better used when it's a dirty asshole.
As soon as said accident is made, it's good to play up the situation by using baby-talk:

Man, to woman, making cute-sy frowny face: "Baby made an assident".

When you are having sex with a girl and your penis accidentally comes out too far and goes back into her asshole. She usually screams in horror.
Girl: AAAHHHH!!!!!

Guy: Sorry, babe. Assidents will happen.

When you confuse a guy wearing emo fag tight pants as a girl with a nice ass. This can lead to one feeling partially homosexual.
Me and dan were drivin'... im like "fuck Dan, look at that ass" hes like "I think thats a dude!"

Me: "Shit, I made another assident!"

We then proceeded to bait him by saying: "hey dude, are you a dude?"

An accident caused by an asshole. Specifically a car assident.
On the way to work, I witnessed a car assident caused by someone texting. The assident caused traffic that inconvenieced thousands of other people. Truly an accident caused by an asshole.

When you do something to piss someone off, then say it was an accident in fear of revenge.
*Purposely team kill in call of duty* Player 1:Im getting you back for that! Player 2:Sorry that was an accident (Really an assident)
