Depends, if you like the taste of vodka, put more than 30% in (and if you want to get messed up faster) but if you fucking hate the taste of vodka do >30%
Sprite. Probably like 3:1. Drank vodka straight once in my life and ended up puking that night so sprite is now the only way I can get it down or else I will start gagging
Yeah and if it's that Phillips crap you will need like a gallon of whatever your mixing with to go with 1oz of it. That stuff is rubbing alcohol. It burns nice though.
Carbonated water and the juice of a squeezed lime. Takes away a lot of the vodka and tastes AAAAMAAAZIIIN! Just blend it so that your friends call you a fag because it is to weak and it'll taste really good. Like 1 part vodka, 4 part carbonated water. Or sumthin.
Almost everything works with vodka as long as you don't try to be the overlymanly man and mix it 50/50.
1) acquire pint glass or similarly large drinking vessel
2) half vodka, half lemon cordial/ cloudy lemonade/ anything citrus flavoured, and as citrus-y as possible so that you can still drink it quickly (but not sprite or any of that type of lemonade)
