"The wrong type of snow" or "the wrong kind of snow" is a phrase coined by the British media in 1991 after severe weather caused disruption to many of British Rail's services. A British Rail press release implied that management and its engineering staff were unaware of different types of snow. Henceforth in the United Kingdom, the phrase became a byword for euphemistic and pointless excuses.

The winter of 1990–91 was a particularly cold winter in Western Europe, noted especially for its effect on the United Kingdom, and for two significantly heavy falls of snow which occurred in December 1990 and February 1991. Sandwiched in between was a period of high winds and heavy rain which caused widespread damage. The winter was the coldest since January 1987, and the snowfall experienced in many parts of the United Kingdom would not be seen again until the snowfall of February 2009.
