I guess I could've used a better phrase.
Anyway, here is the applicable definition with an example:

couched, couch·ing, couch·es
v. tr.
To word in a certain manner; phrase: couched their protests in diplomatic language.

from: www.dictionary.com

Also:

[Verbs] conceal, hide, secrete, put out of sight; lock up, seal up, bottle up.

be concealed; suffer an eclipse; retire from sight, couch; hide oneself; lie hid, lie in perdu, lie in close; lie in ambush; seclude oneself [more]; lurk, sneak, skulk, slink, prowl; steal into, steal out of, steal by, steal along; play at bopeep, play at hide and seek; hide in holes and corners; still hunt.

>Excuse my English - what does "couched" mean in this context? www.britanica.com includes a definition that involves "ambush". Would this be relevant here?
