look up any word, like usuratonkachi:
When you're on the interstate or highway taking a long trip to somewhere ,and there are no gas stations or bathrooms around;and you need to piss real bad so you use a McDonald's, KFC, or Burger King, etc, cup to handle your business.
Me: Man, I need to take a piss.

Isaac: Use that cup right there.

Me: I got no choice but to use the emergency cup.
