1. A man that has sexual contact with any person, more than likely than not, because he has to take it from whomever offers or hints at it.
2. Similar to a manwhore, but without any form of payment offered or received.
3. Similar to a makeout king; however, this is a man so unwanted that he must try to have sexual contact with anyone who remotely bats an eye at him; usually that is a drunken bar girl eye who won't remember him in the morning.
Ever time we take Jake to the bar he disappears with the drunkest, nastiest chicks. Poor chicks, he's such a hisore.
