look up any word, like demisexual:
N. (Professional) cum bucketry is the act/occupation of being a cum bucket, which is a container for semen.

Part of a rather serious insult that degrades appearance, odor and character.
"Oh, I say. I do concur that professional cum bucketry is a good way to turn a profit, and get a good source of protein all in one go!"

"Yeah? Well you look like gem sweaters, smell like the viking museum and major in public relations with a minor in cum bucketry!"
