Juker's

A juker is a carton/gallon of milk that has been spoiled for too long, so companies place artificial preservatives into it to prevent wasting the milk entirely. These preservatives cause the milk to have a tangy taste, which, if consumed at the right temperature, can give the person drinking it a high that lasts for 3-4 days. It’s commonplace in office and work environments to take jukers at the beginning of the week (Monday, Tuesday etc) so the high lasts until the weekend. Jukers are usually sold at your everyday grocery store without the average person realizing.
