Me and my friends are absolutely terrible about this.
For about six months I was living with my then BF (now fiance) 'Wolf' and his friend 'Jay'. They had a very 'bachelor' set up and are fond of some pretty out there humour. Also we are all roleplay geeks who met at a World of Darkness roleplaying game club.
To set the tone, Jay is part Welsh, and one of the running jokes in the house was about his propensity for shall we say sheep romance, and the use of leeks as marital aids.
When Jay found out I had Gypsy ancestry, he managed to get a copy of a defunct but famously clueless/racist book by World of Darkness called 'Gypsies', and that, and applying to me the ideas within, were the source of much laughter for months.
To give you an idea of just how bad this book is:
Gypsies are a 'supernatural template' (a category in these games that includes any non-human, magical entity). So they are in the same category as Vampires, Werewolves, sewn-together animated corpses, etc.
Their power level is based on the 'purity' of their Gypsy blood.
Their skills include stealing, fortune-telling, and cursing, and stabbing people...
We had fun coming up with how the company at the time might have treated different ethnicities - supernaturally mathematically skilled East Asians, with ninja stealth abilities? White people with magic colonial land-stealing powers?
Then we moved on to the imaginary WW sourcebook: The Gays...
