I'm an arcterast myself.

I have always been enamored of the names for the three types of liquid crystal: nematic, smectic, cholesteric. One seldom gets a chance to use them in ordinary conversation, but if one recalls that the first comes from the Greek for needle and the second for soap, there are obvious applications of all three to persons of various temperaments.

Another set of technical terms makes a poem in itself -- the six motions of a ship:

Roll, pitch, yaw,
Surge, sway, heave.

If there is ever a song about seasickness, that could be the chorus.
