Film full of gore

Why can't I be right for once
I thought I knew you but I don't stand a chance
I called you on the telephone
and when you answered you were not alone
And now I have been missing my sleep
I think that I've been getting too deep
I don't like going out anymore
to watch movies with monsters and lizards

chorus:
Your smile ain't so sweet anymore
It's an ugly grin - It's like a film full of gore

You used to greet me with a welcoming smile
I laughed at you and then we kissed for a while
Your eyes were sparkling, your lips were so red
No time to eat - we went straight to your bed
And now you're greeting someone else with your smile
and on the phone it's not my number you dial
When we meet I see you're full of contempt
You despise me and you think I'm a lizard

(chorus)

Why can't I be right for once...
