Person one: Hey do u know what happened to Mrs. Osterhout?
Person two: Yaa she got burned at the stake for numerous accounts of bitchcraft.
A person who is a real piece of work. Someone either really complex or really screwed up or someone almost unbearably hard to handle.
The genesis of the term can be traced from a person being a real piece of "work" or a real "load" and multiple jobs and tasks are often done in "batches." Thus.. a person who is extremely screwed up can be called a "batchload"
I can't believe how badly she was bitchboasting last night when she said, "Oh my gosh, the addition we are putting on our house will be such a pain because we have to move out for six months. What a nightmare!"
