The idea was that you (the defuser) have four symbols and we (the bomb defusal experts) had a set of columns containing symbols, like letters from other alphabets. We all ended up knowing what 'triangle spiderman' was and there's a shared concept of 'apostrophe bum' that's sure to come in useful in all manner of other social situations.
