switch to decaf

Saying used to tell someone to chill out or calm down. Usually used when dealing with overly energetic annoying people.

That guy Sal at the party just wouldn't shut the fuck up and kept talking over everyone, so I told him to "switch to decaf" or leave.

Decaf poisoned

When, unbeknownst to you, the regular coffee pot at work actually contains decaf coffee causing mid-morning head nods, yawns, headaches, and sluggishness.

I would have finished that assignment this morning, but I couldn't because it turns out that I was decaf poisoned. I fell asleep at my desk!
