When your cell phone is dying but you don't have the time to sit and wait for it to fully charge so you leave it in there for a little while so that when you take it out of the charger your phone thinks it has a full battery power.

This often leads to your phone losing battery life and eventually dying on you shortly later after a few texts or calls.
Jane: Why didn't you pick up your phone!
John: It's dead.
Jane: But I saw you take it from the charger before you left.
John: I Flash-Charged it for 20 minutes, and after 5 texts it was done.
