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."
