When a racy picture or situation becomes just a bit racier than was actually intended, esp. when social media is involved or when the photographer/poster is unaware of the error.
e.g., a
wardrobe malfunction or poor camera placement revealing nudity or risque clothing that was intended to be merely hinted at, making "
sexy" or "softcore" material more explicit.
Can also refer to accidental posting of "private" explicit photographs to a public sphere, such as
Facebook.
A portmanteau of "accident" and "exhibitionism."
"Rhonda's just-out-of-the-
shower selfie became a
case of accibitionism when she hit 'send to all' by
mistake... and then realized she was wearing the towel just a little too high to completely cover herself."
