Seriously, WTF?!

Rob Kardashian has been a total shut-in in recent months, but he decided to break his social media silence on his sister Kylie Jenner's 18th birthday. The only problem? His Instagram posts had nothing to do with his sibling's special day... they actually just made no sense whatsoever!

The troubled reality star first shared a pic of Paul Newman salad dressing with the caption "RIP", and then he shared a pic of Colin Farrell on a speedboat in Miami Vice with the caption "MOOD." Are we missing something here?

At least his previous post where he called sister Kim the psycho from Gone Girl was entertaining, but these are just plain weird!
