I think my definition of the word liberal is the classical usage and yours is the colloquial usage, though. Liberal's bare definition is "an advocate for human rights, freedoms, and liberties as long as those freedoms do not infringe upon the rights of others." In practice this is not unregulated capitalism because an unregulated capitalism does not respect individual rights, a democratic state must exist to uphold those rights.

It comes from the Latin liberalis "noble, gracious, munificent, generous," literally "of freedom, pertaining to or befitting a free person," from liber "free, unrestricted, unimpeded; unbridled, unchecked, licentious."

Generally, the sort of people I see complaining about LiBruLZ are Tankies: proponents of eastern bloc dictatorships, or Conservatives: proponents of western bloc dictatorships.

The word "neoliberal" is just some bullshit tankies made up so they wouldn't look so bad while directly opposing human rights, or possibly as an attempt by early 20th century French dudes to oppose laissez faire which already wasn't largely associated with liberalism outside of France to begin with.
