Leech
Leeches are segmented worms that belong to the phylum Annelida and comprise the subclass Hirudinea. Like the oligochaetes, such as earthworms, leeches share a clitellum and are hermaphrodites. Nevertheless, they differ from the oligochaetes in significant ways. For example, leeches do not have bristles and the external segmentation of their bodies does not correspond with the internal segmentation of their organs. Their bodies are much more solid as the spaces in their coelom are dense with connective tissues. They also have two suckers, one at each end.
The majority of leeches live in freshwater environments, while some species can be found in terrestrial and marine environments, as well. The best-known leeches, such as the medicinal leech, Hirudo medicinalis, are hematophagous, feeding on vertebrate blood and invertebrate hemolymph. Most leech species, however, are predatory, feeding primarily by swallowing other invertebrates. Almost 700 species of leeches are currently recognized, of which some 100 are marine, 90 terrestrial and the remainder freshwater taxa.
Leech (computing)
In computing and specifically Internet, a leech is one who benefits, usually deliberately, from others' information or effort but does not offer anything in return, or makes only token offerings in an attempt to avoid being called a leech. In economics, this type of behavior is called "free riding" and is associated with the free rider problem.
Depending on context, leeching does not necessarily refer to illegal use of computer resources, but often instead to greedy use according to etiquette: to wit, using too much of what is freely given without contributing a reasonable amount back to the community that provides it.
The name derives from the leech, an animal that sucks blood and then tries to leave unnoticed. Other terms are used, such as "freeloader" and "sponge", but leech is the most common.

by: Eve 6Tell those stories to me I'm dying to hear the things you've done and seen
Farfetched as they may be
You strike a smile in me
Your stories ring of perjury
Construed with self empowering theme
Suckin' on my brain your the teacher I'm the student
Turning things around your story's not congruent
Tabloid decoys pitiful excuses
Turning things around You're turning things around
A manic stunning scene I'm taking notes your taking me away into your false reality
I know you comfort lies in lying to try to make your life make sense
But you're not making sense I'd say it aloud but I'm not aloud I see your head spin round and round
Broken record talk tonight skip that needle back and forth on your mind wearing out unconvincing lies
Like a seedling dropped from an old oak tree your shade don't hide no sun from me
