Rob Kardashian has been making a point of staying out of the spotlight in recent months, a trend prompted at least in part by his recent weight gain, but the Keeping Up With the Kardashians star has made a questionable return to social media lately with a series of disturbing tweets about his own sisters.

Rob, who recently deleted all of his photos and messages across his various social media accounts, returned to Twitter just days before big sister Kim Kardashian’s wedding with some tasteless jokes about the female members of his family.

On May 20, Rob informed followers that he and his sisters were all spending time together and watching kids’ classic The Neverending Story. What came next was decidedly less innocent — in a tweet that’s since been deleted, Rob wrote, “actually @kourtneykardash is involved in this 5 some orgy @KendallJenner @KylieJenner @khloekardashian GOODnight.”

Ick.

While it’s clear that Rob has been battling some demons recently, we can’t imagine what would possess him to say such gross things about his own family.

If Kris Jenner was upset over Kylie’s blue hair, we can only imagine what she had to say about this!

What do you think of Rob’s tweet? Is it funny or inappropriate?
