Blast some roads

Def 1: Remove pieces or entire sections of paved road with blasting explosive.

Def 2: Eagerly drive around twisty roads, like in the hills of Southern California. The street version of "tearing up the track".

Person 1:Hey man, wanna go blast some roads?
Person 2: Sure, where do you wanna meet?
Person 1: George's pizza at 12:45.
Person 2: Alright, I'll be there.
