There's a wonderful book called "Mrs Byrne's dictionary". It's American, but available in the UK. Any word that's in any way weird, unusual or just plain entertaining is in it. Example - Rectalgia. A pain in the ass. I't's the only dictionary I've been able to sit down with and read. It has the entire "SNAFU" canon; FUMTU (more than usual), JANFU (joint Army and Navy), etc.
