There's plenty of initials that are generally thought of as a no-no - CUM, COK, KKK, FUK, TIT etc., etc.....
...but what about the following.....
Toilet-themed, eg. BOG, LAV, WC etc?
Political, eg. BNP?
Animals, eg. PIG, COW, HOG etc?
Other body parts, eg. BUM?
Would any of the above initials put you off choosing a name that you love for your DC? And what other initials would you avoid?
