Definition:
One who performs an act of fellatio. A mean or despicable
person. Strictly speaking, 'Cocksucker' only refers to
homosexuality when applied to a male. It is also a term
used often when a colleague is 'sucking up' to a more
senior person in power. For example, if a fellow work
colleague went out of his way to please the male employer
to the annoyance of others around then he could be called
a cocksucker.
