Someone mentioned Everclear earlier in this thread and it reminded me of the worst drink I've ever had in my life. My friend's dad makes this drink called Fire On The Mountain. It's Everclear and cayenne pepper powder mixed together. It's just this red liquid and if you smell it, you can just tell you're getting into something bad by trying it.
Basically, he gave me a drop of this and my mouth was on fire but his dad was saying how that's for pussies so of course I take some more. I didn't even take a full shot but god damn did it burn. It wasn't an alcohol burn it was a "HOLY .... SOMEONE LIT A FIRE IN MY MOUTH" burn. There was nothing in his house that could stop the burn and my mouth felt like it was on fire for 45 minutes.
