What is "bucketloads"

Usage examples of "bucketloads".

The rain drummed on what there was of the roof of their haramlek, and dripped down and pooled in the makeshift awnings, which burst in bucketloads down your neck if you bumped into them, and the mist drifted in at every direction through the paneless windows, and the mountains, most of the time, seemed to consist of cloud, or to have vanished entirely.
