In reply to comment: I thought of that too (see in situ)

Mardi Gras is the French way of saying "Fat Tuesday",

the day before Lent, when Catholics are supposed to fast and do penance. It is a Catholic thing and is not limited to any one ethnic background, just different ways of pigging out before the Lenten Season begins.
