Can you help me remember name of this game?

here is a little info.





the game was a monster truck game, it is not one of the new games.


i had it on my old computer, 5-6years ago? i cant remember.


it was kind of weird because you could drive amazingly long, and where ever you wanted!


and i remember you clicked a button, and a voice comes saying boogie man or something.


Please help me.|||Monster truck meyhem!! yeah good game!|||Sounds familiar. I remember playing a monster truck racing game about 5-6 years ago and I always ran off the track and ran over porta- potties. Cant remember the name though...
