f shot - when you're desperate enough to use a ketchup cup as a shot

when you're desperate enough to use a ketchup cup as a shot glass, just to get a little drunk without spending a dime

I used a ketchup cup for a f shot, and I got drunk on soda

My brother used a ketchup cup for a f shot, and now he's talking to the wall

I filled my ketchup cup with juice, it's a f shot and I'm living my best life
