Not a full-sized blunt or a roach, but right in the middle. Slightly, more towards the size of a roach. The blunt is not about to befinished, it is still a size that people are happy with.
Aussie version of "Holy Moly" or variants. Slightly archaic/rural (read: Westie/Bogan etc), but still sometimes used by kids in front of Authorities. Also spelt "hoolEy doolEy"
