Why do they call mixing sodas "suicide drink"?

Question

To be more specific, if you mix several sodas together, such as, when you are at a restaurant, and it's self-service, instead of having only one soda, you mix together all the sodas available ( or, at least a few that's available)

Answer 1

I did'nt know that's what it was called.

Answer 2

because its your own funeral if its bad!

Answer 3

I have never heard of that. Can you e-mail me because I'm bored.

Answer 4

I always thought it was because mixing the sodas together was like mixing up a poison, or at least something that would taste like poison. Therefore, drinking the poison would be like suicide.

Answer 5

Never heard of that before. I have mixed Diet Pepsi & Diet Coke together & nothing has ever happened to me.

Answer 6

Never heard of that, it normally applies to alcohol in the U.K.

It's called also "Never mix the grape with the grain" I.E.

Wine, beer. lager  and spirits. Get drunk v.quick and a v. bad hangover!

Answer 7

never heard it called that before. we used to call it swamp water

Answer 8

I have no idea why it's called that. It's rather a morbid name isn't it? Let's rename it: The rainbow drink! Sounds much happier.

Answer 9

never heard of it, I've mixed before certain sodas in a punch and no one died.

Answer 10

Been there, done that and I've always heard it called that too.

No idea, why though.  Sorry, babe.

Answer 11

Because it usually tastes awful, sort of like killing yourself slowly LOL
