Barking Frog was an alcopop sold in the UK, made using tequila, lime and tabasco. It tasted wonderful, but unfortunately, because it had a stylized drawing of a frog on the front, trading standards insisted that it was being marketed towards children, and had it withdrawn from sale. (This was at the time of a big unfounded public backlash at alcopops, when what the kiddies were really drinking was cheap cider (more alcohol for the pound.))

Anyway, here's how to make one:

Tequila
Dash of lime cordial
A few drops of tabasco sauce
Top up with lemonade

Alternative to lime cordial, slice up a whole lime, and add it.
