Not good. Bad.

The early Jazz musicians would say that a guy could really "Blow" if he had a good sound when playing the horn. If he couldn't play very well then they would say that he was "Sucking" on that horn. That's where the term "Suck" as being something bad came from.
He plays that horn so poorly that he must be sucking on it.

He doesn't blow, he sucks.

(for those under 30 years old) An intransitive verb indicating a negative state of affairs. Could be poor performance, bad weather, illness, general dislike, or any of innumerable negative thoughts.

(for those over 30 years old) Always a transitive verb. Colloquially used as shorthand for suck dick with noun dick understood. Synonymous with blow and bite. Used as an insult; indicates homosexuality.

"To suck" or "you suck" is derived from, or is a shortened form of "to suck dick" or "you suck dick." In effect, it is the equivalent of saying "that's gay" or "you're gay." (You suck dick, so therefore, you must be gay.) This, in turn, comes from the assumption that homosexuality is "wrong" or "bad." Therefore, if something "sucks" it is "bad."

Isn't it strange how widely accepted the term is? Everytime you hear someone say "that sucks" on TV, they are essentially saying "that sucks dick."
Lil' Timmy: Dave, you suck at hopescotch.
Dave: Frig off, Timmy - you are so gay.
