Dead tuna 

After not washing your "kitty" for a couple weeks/months.

Man! Have you smells Jennifer's kitty lately? Man, she's got one nasty dead tuna up in hurr.

Deadtunas 

A group of best friends from Chicago who have fun and love to drink. They get so hungover they feel like fish washed up on shore. Literally deadtunas.

“The Deadtunas are the life of the party!”
“Y’all better be careful or else you’re gunna turn into a bunch of deadtunas”
