I love this. When you do an almighty ablution and when you flush it the water rises up the bowl like it's blocked but then all disappears round the u-bend safely straight afterwards. It gives you both the relief that you don't have to deal with a shit-blocked toilet and the pleasure that you did a poo so powerful it almost brought the plumbing down with it.
I mentioned this to the wife yesterday and not only did she didn't know what I was talking about, but she claimed to have NEVER blocked a toilet in her life.
This thread is about blocking the toilet.
