Any one of numerous genera and species of annulose worms, belonging to the order Hirudinea, or Bdelloidea, esp. those species used in medicine, as Hirudo medicinalis of Europe, and allied species. Note: In the mouth of bloodsucking leeches are three convergent, serrated jaws, moved by strong muscles. By the motion of these jaws a stellate incision is made in the skin, through which the leech sucks blood till it is gorged, and then drops off. The stomach has large pouches on each side to hold the blood. The common large bloodsucking leech of America (Macrobdella decora) is dark olive above, and red below, with black spots. Many kinds of leeches are parasitic on fishes; others feed upon worms and mollusks, and have no jaws for drawing blood. See Bdelloidea. Hirudinea, and Clepsine. 3. (Surg.) A glass tube of peculiar construction, adapted for drawing blood from a scarified part by means of a vacuum. Horse leech, a less powerful European leech (H[ae]mopis vorax), commonly attacking the membrane that lines the inside of the mouth and nostrils of animals that drink at pools where it lives.

leech
n. Among BBS types, crackers and warez d00dz, one who consumes knowledge without generating new software, cracks, or techniques. BBS culture specifically defines a leech as someone who downloads files with few or no uploads in return, and who does not contribute to the message section. Cracker culture extends this definition to someone (a lamer, usually) who constantly presses informed sources for information and/or assistance, but has nothing to contribute.

leech (1)
"bloodsucking aquatic worm," from O.E. læce (Kentish lyce), of unknown origin (with a cognate in M.Du. lake). Commonly regarded as a transf. use of leech (2), but the O.E. forms suggest a distinct word, which has been assimilated to leech (2) by folk etymology. Figuratively applied to human parasites since 1784.
leech (2)
obsolete for "physician," from O.E. læce, from O.Dan. læke, from P.Gmc. *lælijaz "healer, physician" (cf. O.N. læknir, O.H.G. lahhi, Goth. lekeis "physician"), lit. "one who counsels," perhaps connected with a root found in Celt. (cf. Ir. liaig "charmer, exorcist, physician") and/or Slavic (cf. Serbo-Croatian lijekar), with an original sense of "speak, talk, whisper, conjurer." The form and sense merged with leech (1) in M.E. by folk etymology. In 17c., leech usually was applied only to veterinary practitioners. The third finger of the hand, in O.E., was læcfinger, translating L. digitus medicus, Gk. daktylus iatrikos, supposedly because a vein from that finger stretches straight to the heart.
