(Noun) Any type of shotgun (I.e. 20 gauge, 12 gauge, .410, etc), any longer scattergun. The perfect weapon for home defense, personal defense, and is also perfect for the novice firearm shooter in acquiring their target.
"Baby, listen" Nikki said to Shannon, "Here in my world I promise you I will never joke when it comes to the boomstick. If I tell you, 'Lover, please get me the boomstick and get it in a hurry' please know that what I'm really saying to you is 'Get the fucking shotgun quick'".
