A hookers toothbrush
When you don't have a toothbrush and you decide to wash your mouth out with Peppermint Schnapps because your tongue looks like it got run over by a truck.
After spending the night in three different beds, I had to gargle Schnapps just to keep my mouth from exploding.
I had to use Schnapps as my toothbrush because my tongue was covered in glitter and regret.
I tried to brush my teeth with Schnapps. It tasted like a party that went too far.
