Ridiculously Terrifically Retarded
as in thinking, speaking, or acting like a MORON.

When my ex sent me a fb friend request he was being supremely TARDARIFFIC.

Tardrific 

A sarcastic adjective used to describe an occurance or act that is unwelcome and/or troublesome, and is the direct result of someone doing something so unbelievably stupid as to suggest developmental disablement. A portmanteau of "retard" and "terrific".

Jimmy: "Al just split his head open tryin' to ride his bike off the roof and into the pool."
Dad: "Well isn't that just fucking tardrific."
