Someone who likes all their own comments, videos, links, posts, etc... on Facebook. Can be done either sarcastically or narcissisticly depending on the situation.
Eric Glen Meyer is such a selfliker, he even wrote this post on urban dictionary and liked it on Facebook (who invented the word Like). Eric also wrote Like jokes into a live singing play. They were hilarious, everyone "liked" them in real life.
