Australian slang for a medical condition which results from excessive alcohol consumption. Physical symptoms resemble those of a severe hangover (nausea, headache, physical malaise, tremors etc), however the Grog Horrors is accompanied by marked psychological symptoms which include (but are not limited to): profound feelings of self-loathing, regret, loss of self worth, depression, self-resentment. An attack of the Grog Horrors may occur spontaneously but is more commonly provoked by a hazy memory of inappropriate behaviour while under the influence. While the symptoms of an acute attack of the Grog Horrors usually subside within 24 to 48 hours, this condition may become chronic, particularly in the newly single, and in females aged 18 to 30.
Lauren: Where's Melissa?
Sophie: In bed. She's got a bad case of the Grog Horrors after she shit herself in the taxi on the way home last night.
