The origins of this term are rooted in a 90's British TV advert for Rowntrees fruit pastilles. Herein, a crazed Scotsman in a kilt eats said sweets before being galvanised into a frenzied dance, during which he exclaims: "Set the juice loose aboot this hoose!" The vulgar double-entendre implied through this exclamation is what gave rise to the more recent definition of "hoose", around the turn of the millenium.
"This is a bit hoosological"
"Hoose! Hoose! HOOSE!!!"
