Portal Hugger 

This term takes place on the online game known as Runescape, at the Fist of Guthix minigame. This is the term for people who are too big of cowards to face the hunter, so instead of standing in the middle getting charges, they run into the houses and just hop around them. They also get out of the house and just run around it getting 3 charges every 2 seconeds, then when the hunter gets close enough to them, they just get back into the house and teleport to a different portal.

lvl 105 player (hunter): I see you! Die!! *runs at the lvl 110 hunted*
*Lvl 110 gets inside house and hides for 5 minutes*
hunter: Omg what a portal hugger!
