Het Zeta, hes actually correct. From Dictionary.Com:
terse:
adjective, ters·er, ters·est.
1. neatly or effectively concise; brief and pithy, as language.
2. abruptly concise; curt; brusque.
…and brusque means:
1: markedly short and abrupt
2: blunt in manner or speech often to the point of ungracious harshness

So hes right, sorta. Terse is almost never used as a complement. Its a negative term that generaly means someone is being a bit of an a hole.
