what does "paddle your backside" mean? It is a conversation between one military husband and his wife: “All right,” she said evenly, “then stop sayin’ you don’t want me to worry. A forty-eight-hour reprieve ain’t nothin’ to me, Gil. I don’t take no comfort in it. If there’s an emergency ten minutes from now, you’ll be the first one on the damn helicopter, and you know it.” “Damn, woman. i called you ’cause i was feelin’ down.” More of her gentle laughter. “How ya feelin’ now?” “Like paddlin’ your backside.” “Then I guess it’s a good thing you’re callin’ me from the moon,”she said breezily. He laughed. “I ain’t that far.”
