Earphone phaker

[Zipporah Schumaker]

When a person has [earphones] in apparently listening to music, but in reality listening to other peoples conversations, usually about how creepy that person is.
Other people think hes not paying attention because hes jamming to music, so its a very affective [illusion].
Usually employed by [creepers], stalkers, or when a person happens to overhear something about themselves, in which they turn down or off their music to hear what is being said.
Another similar illusion is pretending to sleep. People then open up and start talking about things they may not while one is awake.
