You've several options regarding usage of the word, though the two most popular options remain as "Pay As You Gash" and "Gash: Monthly Periods".
Alternatively, you could appease my family and I by prefixing the word with an adjective in parenthesis, such as "(hungry) gash" or "(cultured) gash" and, a personal favourite, "(fastidious) gash".
That is all. Nightgood.
