Most famously used in Tim McGraw's song "Shotgun Rider," this word means a person's partner in crime, best friend, and the person they want most riding shotgun in their car. No matter what life throws at them or the amount of time spent a part, they can pick right back up where they left off when they're together again. Because he don't want no other shotgun rider beside him, singin to the radio :)
*Shotgun Rider comes on the radio*
Brandon: Hey! You're like my shotgun rider.
Hannah: What's a shotgun rider anyways? Haha
Brandon: You don't know what a shotgun rider is??
Hannah: Nope
Brandon: Haha just listen to the song, and you'll get it.

*Brandon tries to sing the song back to her, but Hannah just laughs and smiles and starts to sing along too*
