A feeling of light-headedness occuring after a parent (usually a mom) spends several minutes blowing on hot food to make it cool enough for a toddler to eat.
Dad: "Honey, why are you on the floor."
Mom: "I was getting Junior some mac and cheese, but I was blowing on it to cool it off. The next thing I knew I came to on the floor."
Dad: "Sounds like momsphyxiation."
