Homemade iced tea; Another way of telling someone you have iced tea that you made, the term comes from the fact that homemade iced tea looks like mop water and the joke that a waiter/waitress that does not like a customer will bring them their iced tea with dirty water usually from a bucket that was used to clean the floor with.
My friend asked me what I had to drink and I told him that I just made mop water an hour ago if he wanted that.
