Ha ha ha, yeah its a drink my mate and I used to drink to get smashed before we went out (in typical student fashion). Its very basic. A shot of sambuca, a shot of apple sours, mix in a glass and down it!!! Very simple but very very effective. For more hardened drinkers there are also tambucas. Same idea only tequila and sambuca.
I did not think i would be discussing this on this message board. ha ha
