I have always been curious as to what the worst or harshest cocktail someone has had. I know for myself, I think the most potent cocktail I ever had was a shot called " The Blood of Satan". It is a layered shot, with the components layered in the following order:
1/2 shot Jagermeister
1/2 shot Goldschlager
1/2 shot Irish whiskey (I prefer Jamison)
1/2 shot Jack Daniels
Z live from Pluto and I have done it in chat a few times. The taste is harsh, but not terrible, but the after effects after a few shots are most incredible!
I haven't had too many cocktails, but the harshest was the Adios MFer I had on a recent cruise. A friend ordered it, couldn't handle it, so I finished it. The combination of headache and brain freeze was rather interesting.
1/2 oz vodka
1/2 oz gin
1/2 oz tequila
1/2 oz rum
1/2 oz blue curacao
1 1/2 oz sweet and sour mix
Splash of ginger ale
Ah! In that case, it would be some Michaeladas I made at home after reading about them in a magazine. Beer, tomato juice, hot sauce... blarrrrrrggggh. I like Bloody Marys, but this was just foul.
As far as hard likker goes, the first "cocktail" I ever ordered in a bar was a vodka and 7-Up. (I thought it sounded "mature.") I think the vodka was rubbing alcohol, and mixing it with 7-Up just gave it a raspy metallic edge.
The most knockout drink I've made that is still drinkable is the "Strip and Go Naked". The danger lies in it's stealth. You don't realize you're completely shtanked until it's far too late.
It's a big-batch punch drink.
-whole lotta ice.
-13 cans of beer. Preferably a smooth(ie characterless), inexpensive beer, like Molson Canadian or similar American low-character swill.
-1 1/2 cans of frozen pink lemonade.
-26 oz bottle of gin
In a large container with a lot of ice, pour the 13 beer. Mix in the pink lemonade. Add the bottle of gin. The person with the hairiest arm in the joint is the designated stirrer. They must use their arm to stir the pot.
Despite the horrible sounding mix of ingredients, this is an easy drinking cocktail. Too easy, in fact...
For a tiki party that Mr. BonzoGal and I threw a few years ago, we made this recipe that knocked people on their tuchases (tuchii?) after about half a drink:
FINK DRINK
1 giganto bottle of white rum- we used some cheap crap back then, we didn't know better.
1 big-ass bottle of decentish vodka- this we knew about so we used something okay.
1 bottle o' Peach Schnapps
1 large package of lemonade mix, Kool-Aid, or whatever flavor powdered drink mix.
1 bottle Boone's, which I thought was a cheap fruity wine, but turns out is a sparkly Zima-like beverage.
Freeze or refrigerate all liquor ahead of time. Find a large vat and mix the rum and vodka.
Then find out the proper amount of lemonade mix for that quantity of liquid and add twice that.
Mix until completely dissolved. Add peach schnapps, Boone's and ice.
Depending on what color your powdered drink mix is, you will barf pretty colors.
