SugarFreeSheilaDotcom's definitions
Something tasteless or intellectually inferior that is devoid of any intelligence - usually in pop culture.  Lacking in refinement and good taste.  Often but not always appealing to the absolute lowest common denominator.
"Sorry, Charlie - the second the silly sound effects and music with the low-brow humor start, I'm out the door.  No primetime TV for me!"
