A phrase referring to when someone's whining,
grumbling, complaining, etc. The mobile refers to the device often hung over a baby's cradle for their soothing entertainment, as it spins around. Thus, "getting him (the
complainer) a mobile" implies he is a
cry-baby.
Mr. Truscott had to listen to all of the crying pleas of the physical education student, but then Marly quipped, "Hey,
GET HIM A MOBILE" and Kemberling and
Herzog were
astoundished by this, as was the entire class. The gym student was INSTANTLY SCHOOLED!
