In Canada, it is commonly known as Pancake Day (or Pancake Tuesday), and in some countries it is known as Fat Tuesday (Mardi Gras)

Shrove Tuesday is the final day before Lent, and it is tradition to eat pancakes or a similar food containing ingredients that are curbed during the forty days of fasting (beginning on Ash Wednesday and concluding on Holy Thursday, the day before Good Friday).
It is also common to forgo one ‘unhealthy’ item/habit during Lent.
The way I see it, this is a sacred sign to eat some sugary, fat food; to enjoy without any associated guilt. Pancakes smothered with butter and syrup sounds pretty good at the moment.
