Selfie Double Entendre 

A selfie double entendre is a picture devised to be or is unintentionally understood in either of two ways. Typically one of the interpretations is rather obvious whereas the other is more subtle. The more subtle of the interpretations is sometimes sexually suggestive. It may also convey a message that would be socially awkward, or even offensive, to state directly. (The Oxford English Dictionary describes a double entendre as being used to "convey an indelicate meaning".)
