Iretarded 

A product that Apple comes out with that is rediculous and has "I" in the name of the product.

Threetarded 

A word to describe a poor connection to the '3' mobile phone network.

The '3' network is highly disputed among most (including 3 customers) to have the crappiest coverage of all of the UK mobile networks.
