'Outside Mom'

So, the billboard is up from the Big Brothers Big Sisters Big Event, at which I was named "Big Celebrity" because I raised more dough than my big-fish, small-pond counterpart at the radio station.
Tom took Alec to see the billboard the other day and he got all excited, and then sad when they drove away. (He kept asking for me.) Later, Alec referred to the billboard as "outside Mom."
