Sleeping in, or delaying waking up at the usual time, is a treat that many of us enjoy on weekends or days off. Some alternative phrases you can use instead of "sleep in" include: oversleep, lie-in, slumber on, snooze, hit the snooze button, have a late start, prolong bedding down, or take a nap later than usual. These terms all refer to delaying getting out of bed and spending more time resting. Moreover, for many individuals, sleep-in is the quintessential weekend luxury, allowing them to recharge their batteries and prepare for the week ahead.
