1. An Internet user that leeches off ISPs -- the sort you can never
provide good enough services for, always complains about the price,
no matter how low it may be, and will bolt off to another service the
moment there is even the slimmest price difference. While most bottom
feeders infest free or almost free services such as AOL, MSN, and
Hotmail, too many flock to whomever happens to be the cheapest
regional ISP at the time. Bottom feeders are often the classic
problem user, known for unleashing spam, flamage, and other breaches
of {netiquette}.
2. Syn. for {slopsucker}, derived from the fishermen's and
naturalists' term for finny creatures who subsist on the primordial
ooze. (This sense is older.)
