I was thinking more of the broadness or boxiness of your average kite. On the other hand, kites don't weigh so much, so maybe I shouldn't take any offense at all.

"That Steve, he's so light, he could float on air."

"Yes, but he's so broad across the shoulders, tapering down to his feet."

"I heard his tail got caught on a chain-link fence!"

"That must have hurt! He should wear pants!"
