look up any word, like hipster:
A person who takes advantage of the fact someone has either fallen asleep or briefly passed out. The sleeping sneeker will usually take advantage by doing something sexual to the person without them knowing
Chris is at a party, the girl next to him has passed out due to to much alcohol, chris then takes advantage of the situation by sleeping his fingers down the girls pance and fingers her vagina. He is then forever known as the sleeping sneeker
