I've never heard anyone actually label it, maybe it's because girls are naturally more touchyfeely than boys. Lol i made that sound so sexual but basically girls hug each other and such all the dang time. Like no sense of space girl lololool
somehow "womance" sounds a bit silly...^^ i mean bromance comes from "bros" and that means something like friendship between men... but "womance" does not have such a origin (atleast i, for myself, don't see it)
it happens more naturally(they get along naturally) to females so it is simply romance. They like food, you call it <insert nationality here> food but in their country they simply call it food. to put it short men want to name everything around them.
