A word that, in regional origins, comes from the city of Bristol, England and when said assertively or in a commanding tone, denotes a sense of comfortableness within ones friendship group even if hyperactivity is unsociably present and the delivery of such a remark is not, as the majority would accept, delivered with the right timing.
NOTE* very popular with groups of young men whilst drinking alcohol, and now becoming more popular with groups of young women on nights out.
(a few close friends are drinking and getting a little boisterous, and although in a crowd of people that probably don't appreciate the following, one of the group bellows:) "HUSK!"
which then immediately gets the rest of the group laughing raucously and immaturely, followed by other "HUSKS!" bellowed out by daring members of the group.
