TGIF

Starting in the United States, it has become a common expression of relief at the end of the work week and anticipation of relaxing or partying over the weekend. The phrase was further popularised by the 1978 movie starring Donna Summer, Thank God It’s Friday. The phrase has also become common for advertising and promotional materials. On college campuses beginning in the 1970s, the phrase (sometimes shortened to "TG") became associated with Friday afternoon beer parties, usually held outdoors.
