- Tending to balloon
1861, Various, Atlantic Monthly Volume 7, No. 40, February, 1861:
- His low-cut shirt-collar and narrow silken neck-tie were in the style called "English," as quite decidedly, also, were his cross-barred trousers of balloony build; nor, although thus flinging himself for diversion into the vortex of the lower crowd, had he foregone the luxury of tan-colored kid gloves and patent-leather shoes.
2004 July 2, Fred Camper, “The City, Brick by Brick”, Chicago Reader:
- Above the word is part of "Central," rendered in a dated balloony script, underlining the archaic nature of Gross's subject.
