Faceblitz
Faceblitz is when someone who hasn’t been on Facebook in ages logs on and starts liking everything, commenting on every post, and acting like they’re the most important person ever for about an hour.
"I’m liking this post. Also, I’m liking this comment. Also, I’m liking this like."
"Why did I not update my profile in 5 weeks? I’m so sorry."
"I’m commenting on every photo like I’m the main character."
