Larger, cider and blackcurrent, sometimes refered to as a snakebite and black, diesel (scotland) or even "Jungle Juice". The combination of sugar and alcohol goes to some peoples heads and as a result some publicans refuse to serve it and claim it is illegal.
A favourite of Irish and English Goths/metal heads/rockers and Austrialians.
If visiting America be careful! If you ask for a snakebite in an Irish bar you may find the taste of Gunniess making it way in to your mouth. Gunniess is used instead of larger by some, a vile practice.
"Snakebite an' black!" *Barman pours a messure of black in to a pint glass and draws off half cider and half larger and relives you of some currency.*
