OMG this is amazing:
List of terms for gay in different languages.
I may or may not write more on this, but I am amused by the linguistic universality of [large vehicle]-[gay woman]. Like the equivalent of the English "diesel dyke," I guess, except it's like "tractor dyke" and "truck dyke." And then there's like "huge manly shoes", which apparently means "dyke" in portugese.
I'm not sure WTF is up with the word "towel" being a synonym for gay, either.
In any case, some are funny, many are inexplicable (ah, yes, a beechnut. I can see why that would mean "guy who likes guys"), and most of them are derogatory, or at best, neutral. Only a couple of "positive" ones.
