When you have a facebook account and someone, usually a signifcant other, or someone that wants to be held in a higher postion in your pecking order feels the need to post, like, or make comments on your facebook page constantly in order to "mark their territory".
Akin to a dog "marking his/her territory" like a fire hydrant with urine.

Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
