babysitter worthy
Similar to Seinfeld’s Elaine’s term sponge-worthy.

This term is attributed to when a single mom must decide whether a date is worth the cost of a babysitter. If the planned date either 1) costs less than the cost of the babysitter or 2) the suitor is not highly desired; the single mom should decline.
