I never did find a good set, so I have made my own. This one is in Australian English, (as the possibility of finding one of those was even rarer!), though I will soon add a British English and American English version to localise the language (so we don't argue what a thong is (; )
There are some pictures available online as posters, but they always seem to be made out of 1980's (non-matching) clipart or hand drawn black and white drawings from when men wore their pants around their bustline. So I cut mine out of cute paper to give them a fun, bright, quirky look and feel, and so they'd have a bit more heart.
