Means: Someone who stays at home and doesn't go out
Usage: "Dave, work? No way, he's a yardy, always at his endz - a proper wasteman"
What a world we live in when the name of a once-feared, all-powerful Jamaican crime syndicate with international scope and a penchant for firearms can be reduced to meaning a slightly lazy or unadventurous pupil.
Proof that the Yoof's continuing evolution of the words we use doesn't hold anything sacred. To be uttered in conjunction with, or instead of, previous Yoofspeak classic "wasteman", "yardy" is a derogatory term and a literal take on the Americanism "yard", meaning someone who rarely leaves their house. But for why?
Maybe they are just terrified a member of a Jamaican crime syndicate may "waste" them with one of their firearms? Well, with everyone all "wasteman" this, "yardy" that, you can see why there could be confusion.
