I call OTC as just outside the club. Some construe it as sex in a hotel room, I just call it outside the club. I once routinely met up with one dancer or another in times past and we were just hanging out as friends most of the time.
I believe many on here call an ATF just one of your most favorite dancers. It doesn't mean you are doing her in my opinion. Some may but I have had several favorites that didn't go that far.
ROB simply means RIP OFF BITCH to me. A dancer promised you something whether that was dances for money or something else and she flat out lied to you and ripped you off not providing what she promised leaving you poorer and angry. Often warning signs are promising something that sounds like a really good deal. For instance you get 8 lap dances and it only is going to cost you $80 when the typical price is often $15 to $20 per dance. She makes you pay up front, secretly picks up the money during the dance, and then undoes your belt and suddenly says something about the bouncer calling her away in the middle of the second song. You fasten your belt and she's gone with your money. Other terms for ROB are thief and con artist.
