A Cock Biter is an explicative, derivative of the term 'Cock Sucker' so termed for increased emphasis, such that where an individual could be termed a Cock Sucker but still be good at sucking cock - alternatively a cock biter is not only one who puts cocks in their mouth, but they are also not doing it right.

As such a cock biter is a failure as a cock sucker, and of the very worst class of all cock suckers.

A cockbiter is a person who applies the element of "cockblocking" to every aspect of their life. As in, they will not let anyone else get some figurative pussy. The most painful thing for a cockbiter to witness is another human being doing well, being successful, or just generally having a good time. Cockbiters get this way because they are jealous of other people's success. A cockbiter is usually a cockbiter on a subconscious level, although this is debatable, as Cockbiters are usually already of a questionable intelligence.
