A good measure of nasal phlegm, hoiked up and spat on a ceiling. The desired effect is to have a thick, glutenous ball of spit slowly hanging into an icicle type installation, the better right above teachers desk. Joy occurs when the phlegmsicle starts its journey and becomes ever more elongated, until the tipping point is reached and the phlegm disconnects with the ceiling and becomes an earthbound projectile of slimy green snot. Orig. Liverpool UK
