A spod is a bit like a geek, or a nerd. Perhaps a bit less geeky than a nerd, and a bit less nerdy than a geek. A spod isn't instantly recognisable, at least not as a spod, or a nerd or a geek. A spod will reveal themself only to other spods or very trusted loved ones. A spod has spoddy mannerisms.
I'm glad that's all cleared up.
