Oh, so you pretty much spent the entire day pulling a BP . . .
When you drink a glass of prune juice and you have a bowel movement that seeps out slowly and you just can't get it to stop. A true BP is when the state of your gastrointestial system is (B)eyond (P)epto. The stool is generally dark in color and is reminiscent of the crude oil in the Gulf of Mexico. Depending on one's hygeine, dead crabs may end up in the toilet as well.
Used to describe someone who makes a snafu out of something deceptively simple. Refers to the 2010 BP oil leak in the Gulf of Mexico. Can also be used in the feminine sense, as in "she could work for BP."
