can somebody tell me what this is?

I was doing a search of my username, Aidan, because I wanted to locate the last post I made on a specific thread to see if there'd been any more activity on that thread- and I wasn't signed in and didn't know if I needed to sign in, as I didn't yet know if I was going to respond or not to any potential activity on the aforementioned thread.

Anyway - this phrase- 'Aidan channels Tth' popped up, so out of curiosity I clicked on it - having no idea what it means or from where or whom it may have originated - and apparently there's a whole forum named 'Aidan Channels Tth' (although there are no threads in it).

I don't understand. Can someone explain this to me please? I'd be ever so grateful.
Thank you in advance for any insight you might be able to offer.
