I hear something like "imbres su vehementer". This person usually has an excellent voice & pronunciation, but not on this one. Please check the recording. I used the correct answer, but I was just guessing :-)
Imber gave rise to imbrex which is a kind of curved roof-tile, and that gave rise to imbricatus which is "arranged like a set of roof-tiles," and that yields Portuguese imbricado. I am not aware of any other descendants.
