An individual that uses electronic media, computers, cell phones, etc. to expose themselves physically to unsuspecting friends, acquaintances, and strangers. They typically send suggestive photos of themselves, or photos of their private parts that are unsolicited and unwelcome. Generally the content is objectionable and would be considered lewd if exposed in a public setting.
John just sent me an unwanted picture of his penis on my cell phone. Electronic Exhibitionism is so lame.
