Salmon Cannon is an absolute beast of a fisher woman. Also known as Annie Birch. You may find Annie drinkin a bud and catchin a buzz as she reals in 20 pound salmon. Which she takes home to her lucky booty call of the night as the two girls get it on and eat God’s wonderful creation- Salmon
“you ever heard of that girl annie birch” “oh yeah she’s a true salmon cannon” “ah true she sure does get around!”
