Sacred Roll
1) While visiting a foreign bathroom; Finding that last roll of ass wipe under the bathroom counter as you penguin walk from the toilet, panicked that you will be exposed by having to ask for a fresh roll.

2) When cash is real low, the last roll in the house, that must be rationed carefully and used for emergencies only. (No doubling up)
Foug: Hey, you got anymore shit paper?
C: I don't know, wait here last one man.
Foug: ahh, Sacred Roll
