when one person, typically female, dominates the facebook wall of her significant other in order to leave her mark on that person and keep other potential love interests from pursuing him. similar to the logic behind a person, typically male, giving a significant other a hickey.
she posts an inside joke on his wall, followed by a heart, every 4 hours. clearly she's giving him a facebook wall hickey.
