Yeah, but it's just 'English' btw - although American English is most definitely a foreign language!

The earlier posts on the World Cup of pet hates does have extensive posts on these terms but, basically, the portaloo refers to a brush-washing device available to buy. Doorstop bases refer to those unfeasably massive lumps of rock or whatever that some gamers like to balance wargame figures on in the vain hope that it makes their figures more interesting but really should only be used for display models that should never be used on the tabletop.
