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.

Get the facebook wall hickey mug.
Commenting about facebook on facebook, or when a group of people are having a discussion in a comment thread, and someone comments with, "This is the best/worst comment thread!"

Interrupting the flow of conversation and your suspension of disbelief that you actually have a social life.
Dickwad Dave: Fuck yea, I made waffles this morning. And took a picture.

Cunt Julia: Hope you enjoy your waffles Dave, as they're the last ones you get to eat without knowing you have HIV. Oh by the way, about last night, I HAVE HIV.
You and 127 like this.

Dickwad Dave: Jokes on you Cunt, I wore a condom! Now they're righteous waffles.

Cunt Julia: You drunk slobbering fuck, you tried to wear a magnum condom on your midget dick and just ended up stuffing the condom up into my twat like god damn canon packing.

Dickwad Dave: Fuck you whore! Why'd you let me fuck if you're an infested skank!

Cunt Julia: Me being half passed out in the guest bedroom does not count as "Let you fuck" you god damn rapist.

Worthless William: Best comment thread ever
