If English is a second language to you, you may not understand the phrase “wake up and smell the coffee”. It is an English idiom, like “Bury the Hatchet” (which means “leave bad things in the past”).
“Wake up and smell the coffee” means in English “Pay attention!” or “Realize this!”
It is sometimes a very mild insult.

We hope this a help to all our foreign readers!
