Recall this Comey tweet and Q's translation of it in his post #1646.
JC Tweet Translation:
Special Agent Andrew McCabe stood tall over the last 8 months [DO NOT TALK], when small people [SHEEP] were trying to tear down an institution we all depend on [COVER]. He served with distinction for two decades [WE OWN YOU & YOUR FAMILY]. I wish Andy well [187]. I also wish continued strength for the rest of the FBI [GENERAL THREAT TO OTHERS]. America needs you [ACTIVATE SLEEPER CELLS].
So Q is mocking the tall drink of dirty water, but not about his height. About his prior use of "stand tall".
