That includes several of the highest possible cards for the given hand; as opposed to smooth.
ADDITIONAL INFORMATION: Example: In lowball, a hand of seven could be made with any of several possible combinations, 7-6-5-4-2, 7-6-5-4-A, 7-6-5-3-2, 7-4-3-2-A and many others. 7-4-3-2-A is the best seven because it uses the lowest possible cards. 7-6-5-4-A would be a rough seven because it uses several of the higher cards that would still be referred to by the same rank.
EXAMPLE: "I raised with my rough seven, but my opponent beat me in the showdown with a smooth seven."
