Means Gay and Retarded. Originated because a certain someone's so called GF did not like either word. Now, unbeknown to this so called girl, we are now able to use the words, "Gay and Retarded" freely, without the fear of prosecution of our so called "significant other".
This is effin Grizdal. Or.... You're so effin Grizdal.
