the pits(redirected from that's the pits)
A very unpleasant or unfortunate thing, situation, or circumstance. I'm sorry to hear about your divorce, Sam—that's the pits! I worked as a telemarketer one summer, and it was the pits.
The worst possible situation, as in Spending your birthday working alone is the pits, or That job is the pits. The allusion in this term is unclear. Some think it refers to coal pits, others to armpits, and still others to the area beside an auto racecourse, also called the pits, where cars are serviced during a race. [Second half of 1900s]
