Arguably the most popular phrase spoken by uncle grandfather in the cult animated hit "perfect hair forever"

Uncle Grandfather used this phrase when acting out a scene between a cake, and a vacuum. The cake was a "chamber maid" and the vacuum was "pleasently surprised".

During the action, the cake was humping the vacuum, and uncle grandfather anthopomorphised the cake saying, "frost my bag, frost my bag, frost my bag, OMG!"
