Can i just check something?

A few years ago, some mates and i used to use the word clunge, and it's given me a fair few chuckles to hear it again.

BUT people seem to be using it as a euphemism for a lady's genitalia. I thought that it referred to the secretions of said bits, and this makes much more sense to me.

Has this debate come and gone already and am i just shouting out my ignorance/lack of being 'with it'?

Thanks
