What is Keep It Up?
1.
If said in a cheerful, praising tone, it means "You're doing great, continue the good work!"
If said in a warning tone, it is a threat that means "Stop it right now, or reap the consequences!"
Praise: Wow, you've lost 35 pounds on that diet! Keep it up!
Warning: I have had all I can take of your whining! Do you want a spanking? Keep it up...!
