Actual drink —
Sloe Gin Fizz
Echhh! tastes like spoiled Hawaiian Punch. 
How can anybody tolerate it?
I’ve mixed some off combinations, but nothing that topped that!
Sambuca and soy sauce. Though the night we got hammered on 4th of July one year and had a contest to see who could eat the most raw eggs (cracked straight into the mouth) followed by a shot of cheap scotch was a close second. We figured the scotch would handle any incipient salmonella. Or the inevitable barfing later.
No one won. We ran out of eggs
Dr Pepper & peppermint schnapps. After splitting a bottle of rum, it seemed like a good idea.
It wasn’t.
One time all I had was milk and vodka. It tasted pretty bitter, until I had an idea to add honey to it and call it a “Promised Land”, although the alcohol would be better replaced by some fig-based liquor.
I’ve seen someone drink Vodka and Milk of Magnesia. Called it a Phillips Screwdriver.
There seems to be a Dr Pepper theme at play here.
