Top definition
Someone who gets aroused at the slightest thing. But unfortunatly cannot maintain an erection for more than four seconds. They tend to be people who shout out "porn" every time they see visable flesh other than the face. This happens because they are so sexually frustrated that they find even the slightest thing erotic.
