Up until yesterday I used to believe that the line in the song 'Seasons of love' from the broadway production 'Rent' went "In daylights, in sunsets, in midnights, in cups of coffee, In MINGES, in miles
in laughter in strife". Minges meaning a slang word for vaginas. I figured that because Maureen and Joanne were lesbians in the play, they would measure their year in how many people they have one night stands with.
Yep, Stupid I know! But when I listen to the version I own it really does sound like it!
