An unfunny, smallminded euphemism for a lesbian used mostly by "men" unable to relate to women in a normal way.
A woman who tends lady gardens, ploughs the furrow manually, enjoys the fruit of the bush, prefers melons to plums, etc.
I once asked out a female horticulturalist, but she turned out to be a girl gardener.
Going out with Tony on Saturday.
That's your third date. You made an appointment to take care of your girl garden?
Hellz yeah, it's like Chewbacca moved into my pants.
