What does Sack mean?

‘Sack’ is slang for ‘Bed’

When you hear people say “sack” in relation to sleep, they’re actually referring to their bed. It’s a casual phrase often used in conversations, text messages, and even on social media. For instance, after a long day, your buddy might message you saying, “Too beat, gonna hit the sack.”

Or, your mom might comment on your late wake-up time, “Wow, 11 am? Tough time getting out of the sack today, huh?” It’s a common and much-used phrase in everyday language.

The origin of this term isn’t entirely clear, but it can be traced back to the 19th century. Back then, people often slept on beds that were essentially sacks filled with hay. This is also the origin of the phrase “hit the hay”, which also means to go to bed. The connection between the sack and sleep is quite literal from this perspective.

I wish I could, but I’m so tired. Gonna hit the sack early tonight.

No worries, get some rest. We’ll catch up another time.

Thanks! I really need to recharge in my cozy sack. Have fun at the party!
