A phrase that is commonly used in a belitting fashion. The phrase was coined in response to a certain kid, Rutzman, who habitually does retarded things. The "GG" is said to bring shame to a certain person, however, when adding the "Rutz" after, the phrase multiplies its disparaging connotation.
This expression is used most commonly when a person, or group of persons, does such an act deemed unintellegent by people with an SAT score of 870 or lower. (This also requires at least one ugly red-headed kid in the group. See Rutzman).
An exteremely ugly red head with horrible acne on both the facial extremeties and other various body parts (no need for details), also has greasy ass hair, and slurs words.
