A ladprechaun is a midget chav/lad at the end of a rainbow, however, instead of hoarding a pot of gold, their pot, contains only pot, knives and Nike, they will attack you should you find them, they are commonly dressed in green Nike and Adidas clothing, when not guarding their pot of pot, knives and Nike they will hang around in malls, asking someone for a light, their national language is Pig Latin.
Person 1: Hey look a rainbow! We'll find gold!
Person 2: no! Wait, there's a ladprechaun there! you'll get stabbed!
Ladprechaun: Stay away from me lucky shanks!
