Bisky is
something that is so "banged" or "damaged" that it is falling apart. Biskylicious is when the object is SO bisky that it actually becomes "Awesome". It is derived from
skateboarding, when the tail of the skateboard becomes flaky from use and resembles a
biscuit. When used with motor vehicles the term is changed to "biskitwagon" or "biskitmobile"
"dude your skateboards bisky!"
"dude your
shirt is freakin biskylicious!" when describing a
shirt that is worn but is possibly your favourite, looks good and retains
character because of its age and damage.
