A simple cocktail of coke and vodka.
Take
one can of coca cola, drink it down about a tenth of the way and apply vodka liberally (or to yuppie taste) into the can. As you get further down,
add a little more, a typical hand grenade will have contained about 4 shots (and a good 2 others spilt on the floor) when drunkenly poured and drank correctly.
The term handgrenade comes about because as you top it up you should be left with a near pure
shot of vodka with a tint of coke at the
bottom, blowing you away.
Best enjoyed with a fine vodka
like Absolut. Absolut with lemon if you're kind've fruity.
