A person who is so needy they create a force akin to
gravity, that pulls everyone's attention, energy, and
cash into their gaping maw.
Being a hose, such as "
beer hose", means one who sucks with reckless abandon.
Do not invite Sarah to the
party. She is a psycho hose
beast who will talk about herself ceaselessly, drink all the
beer, and force you to buy her things.
