Another stupid conjoined word for a famous Hollyweird couple. It is the combination of Tom Cruise and Katy Holmes. Also, when Katy Holmes became visibly pregnant, her belly and the fetus within it were known collectively as the TomKat Bump.
The term originated in the gossip rags.
Did you see TomKat where all the other Hollywood freaks hang out? I wonder when the TomKat Bump will be born?
The very current couple otherwise known as Tom Cruise and (formerly) Katie Holmes. These two were in the spotlight for most of '05, during which they met, became a couple, and got engaged. They are now expecting "TomKittens", and will be married either in the summer or fall of '06.
TomKat were recently visiting Kate's parents, but left 3 days early due to some issues between Tom and Kate's father.
