Coffee Condom 

A cardboard sleeve made to insulate to-go coffee cups.

I did not use a coffee condom and my espresso got cold. I should learn to practice safe drinking.

Coffee Condom 

The name for the sleeve that goes around your handle-less paper coffee cup to insulate the drinker's hands from hot coffee.

Similar to how a latex condom is designed to protect you from sexually transmitted diseases the "coffee condom" is designed to protect your hand from the hot cup of coffee.

Do you need a coffee condom for that cup?

Coffee condom 

The sleeve that goes on a steaming hot coffee (often from a drive thru) so you can hold it without burning your hand.

May I have a coffee condom for the cup to keep from burning my hands please?
