Fear or phobia of being "Fleishig".
Jewish law requires that one wait six hours between eating meat and dairy. Many religious Jews have thus developed a phobia for eating meat during day hours because they "might" want to eat something dairy later on in the day.
("Fleishig" is the Yiddish word for "Meaty").
I'm starving. All they had was meat - which I naturally couldn't bring myself to eat because I suffer from a severe case of Carniphobia.
