Not necessarily a full moon, but nearly - gibbous. So named because it's
nice and bright so you can see what you're upto whilst doing somebody's
drum at night.
Actually a pain in the arse because it makes it more likely that you would be
seen clearly whilst perpetrating the crime.
Gran: Burglar's moon tonight...
drummer: Yeah
Gran, but I'll take a maglite anyway, for when I get inside a place.
