A phrase used, either ironically or seriously, to reserve the
front passenger (a.k.a. shotgun) seat of a vehicle for yourself, under the pretense that you deserve to ride shotgun because of your
good looks. Girls are more likely to
say this than guys, but either sex can use it.
Sean: "Shotgun!"
Erin: "
Nope, hotty gets the
shotty!"
Sean: "WTF? Whatever, but I pick what we listen to."
Brigette: "ROFL you guys, just get in the
car!"
