Evolution of a Nickname

Jack becomes
Jack-man-doo, which of course leads logically to
Thomas-man-doo, the last two of which Anna now refer to collectively as

the mans.

As in:
"Look! The mans are playing with their chew toys"
"The mans are eating lunch in their high chairs"
"Yikes! The mans are crawling into the bathroom"

I even find myself getting into it. Jack-Man-Doo easily becomes JMD, who sounds like some really hip downtown DJ, as in "Yo JMD! Let's kick it!"
