I got my hands on a 1993 Modern slang dictionary, published by Oxford university press.
Way bigger and more complete than the dictionaries I've seen online (though I haven't really looked that hard).
So I'll be feeding my readers the words I liked.
Here, for example, is some toilet humor.
Accident
1)An unintentional act of urinating or defecating.
2)A child whose conception was not planned
