There´s also an off chance that he meant a chat room. Sometimes in haste the natives abbreviate an entire expression by using one word. That would be the case.
Example of room, used by chat-goers:
At 17 I met a guy in a chat room for a date and he was great. We hit it off immediately in real life.
The above sentence, said in informal/colloquial way, could well be mentioned like this: "it was a great room for a date.", for instance.
Obviously, the other person would know that it was about the subject of chatting online, in said rooms.
Again, as it was mentioned before, without context we are just in the guesswork realm here, the whole thing gets pregnant with possibilities...
