• Don't Be Cheap. Exclamation used when someone is being cheap...and you want to tell her not to be, but don't feel like spelling it out to them. Instead you use this acronym that she is clueless over and she wonders what you mean.
• Example: Situation: Chris drank your last beer and won't even offer to buy more when you mention that you are out of it.

You: Ahh, I'm out of beer.

Chris: That sucks.

You: DBC!
