A hagan is someone who enjoys sexual relations with females, males and animals alike. A hagan also takes his prey by force when usual methods are not fruitful. Usually small in the reproductive area, a hagan often makes up for this by being a mash up at a party then blaiming this state for under performance in the bedroom. Because of this, you may sometimes hear a hagen being refered to as 'Ant' or 'Ant cock'...
"look at Ant (hagan), he is attacking people in the street again"
"Oh my god, look at that ant hagan, he is so messed up his cock and balls look like a two year olds"
"That Hagen needs locking up to protect the public and animals of the world from physical and emotional violation"
