Sometimes, as with tsuyudakudakudaku ("dripping with soupiness"), people will request that the daku, or amount of tsuyu, be exceedingly increased.
The origin of tsuyudaku comes from Japanese businessmen (salaryman) on their morning commute to work who, due to time restrictions, ask for extra soupy gyūdon (gyūdon tsuyu ome ni) so that they can eat it quickly.
