Berf (unit)

a measurement of how much dog hair has been vacuumed by unit; when emptying a vacuum. A single vacuum emptying would equal one single "Berf". Two or more would be "Berfs" (plural).

"We need to comb "Bertha Maye" tonight, she is shedding like crazy! I emptied five whole "Berf (unit) 's" into the trashcan before I finished vacuuming."
