(n.) a person, most likely also a bust down, that goes to Clybourne bar (Cly's) at the University of Illinois at Urbana-Champaign on a weekly basis (most likely Thursday) to have pee and fecal matter fall on their heads from the pipes that will most certainly be leaking.
That girl goes to Cly's every Thursday - she's such a Cly's-rat. She'll probably give you dome, assuming you want some from her since her hair probably smells like dookey.
