A sickness, usually overcoming you for one day.Common in girls.

flagamps can occur when your period is just ending, but you still have cramps. Your abdomen still not feeling well, you eat a small amount of food, But later, your cramps will go away. Seeing as you only ate a small amount during the beginning of the day,your cramps turn into hunger. You think its still cramps, so you continue not eating, only to make matters worse.
