A place for relief of bodily waste out of the anus of the butt. It is usually a low white porcelain "seat" in which you can safely "drop the Cosby Kids off at the pool." <-- this expression can be used to explain politely that you have to do your business.
"Excuse me John, ill be back in a few i just have to drop the Cosby Kids off at the pool."
"Man i had to flush that toilet three times and it nearly sent off the smoke alarm."
