An ice pop or ice lolly is a frozen water-based dessert on a stick. It is made by freezing coloured, flavoured liquid (such as fruit juice) around a stick.
Actually, not a slang word.

Alcoholic drink, made from 3 shots of blue curacao, vodka and bacardi. Mixed with a lemon VS. Slips down easily and tastes no way near as alcoholic as it is. (Duely named as it resembles the blue ice pops you used to eat as a child, that has been defrosted and poured into a glass)
