Cocksy-worsy

Hello!
What does the writer mean by "cocksy-worsy" at the following sentences by Saul Bellow in Henderson the Rain King?

After the fifth or sixth day the character of the ground changed somewhat. There was more wood on the mountains, although mostly the slopes were still sterile. Mesas and hot granites and towers and acropolises held onto the earth; I mean they gripped it and refused to depart with the clouds which seemed to be trying to absorb them. Or maybe in my melancholy every thing looked cocksy-worsy to me.
Thank you.
