When a guy gets hard just from light physical contact with or just being around a person that he is crushing on. It happens without warning and can sometimes create an awkward situation if the other person notices.
Jimmy: Hey Daniel! Me and Jessica are having an arm wrestling contest. Do you want in?
Daniel: Nah, with Jessica there I'll just get another Accidental Boner.
Jimmy: Jessica is pretty hot. I understand.
Daniel: Nah, with Jessica there I'll just get another Accidental Boner.

When the hot neighbor chick stands naked and unaware in front of her apartment window, and you accidentally catch a glimpse.
"Dude, I had the best morning. I stumbled into the kitchen to get coffee, and that hot blonde next door gave me an accidental peepshow."
"Man. I wish I'd been there."
"Man. I wish I'd been there."

Having sex with someone when you honestly didn't intend to, or are trying not to. Not always a bad thing and is no big deal because 'hey, accidents happen'.
I went over to my ex's place to drop off some stuff last night. We got talking, one thing led to another and we had accidental sex.

A spur-of-the-moment decision to do something that you should not be doing, which you then deny when someone finds out about it by saying it was completely on accident.
Girl 1: Did you steal my favorite shirt? I found it in your room
Girl 2: Oh! Uhh, I must have, um, packed it in my bag by mistake when I was leaving your house! It was on accident!
Girl 2: Yeah, right, accidentally on-purpose!
