Maybe three weeks ago, I revealed a Brain Game to be "a poem wot I writ myself." As a bonafide glutton for punishment, I'm doing it again. So here's a riddle. (Yes, it's bad.) Good luck!

Scratch the "Frosty," slide the "the"
This word would fit right there
And if you set it off, you'd have
Hamburger everywhere

What's the word?

Here is the ANSWER.
