GIGO is an acronym which stands for 'Garbage In, Garbage Out'
It tends to be used when talking about data entry and databases.
Bascially it means that if you enter inaccurate or wrong data then you have really entered garbage. Then when you want to do some queries, searches or reports, you will only get incorrect, wrong or inaccurate data out - garbage.
