I have a quote here, and I'm curious as to what people would think it is describing (in functional terms).
"Was Mario a well behaved child? 'It was as if he had one of these', says Pierrette [his mother], indicating a halo over his head. When young Mario's halo slipped, it uncovered a stubborn streak more suited to a pack mule than a cherub. He was, and is, a rotten loser, whether at Monopoly, cards or basement hockey. Tantrums followed losses. 'If Mario lost, it would be as if a hurricane went through the basement,' says Jean Guy [his father]."
