Self-directed rehab. Intended to facilitate change within oneself, whether in regards to bad habits or addictions.
"Where the hell has Jay been at?", "I haven't seen him, I think he went into mehab."
The term used to describe the increasingly trendy self-promotional gimmick of checking into rehab in a desperate bid to gain or regain fame.
It seems that more and more people are becoming famous for bad behavior these days. Release a sex tape, sleep with a married celebrity, check yourself into mehab, and… boom! Just like that you have your own show.
