liquor up

After dinner, if all that I hear be true, the gentlemen occasionally drop into the hotel bar and "liquor up."

After the end of the time sufficient cold water is added to bring the volume of the liquor up to 10 gallons.

Say, let's liquor up once more before we go to see the elephant.

Everybody seems to feel called on to liquor up, this time o' year.

Moreover, he has to be at "the bar" every night, and to "liquor up with all creation" in the small hours.
