Next day wrinkles are wrinkles that appear on your face after a night of hard laughing your ass off.

When someone doesn't respond to a message, particularly pertaining to snapchat, until the next day. And you have no idea what they are talking about.

National See You Next Tuesday Day is observed on October 20th, commonly in the floral industry. The day is celebrated by making certain to bid farewell to deserving customers with, "See You Next Tuesday Day!" even when there is no intention to follow through when next Tuesday arrives!

Cool, good, delicious, fresh, better than expected. Like when fried food stays crispy til the next day, it’s unexpected and delicious.

Very hungover, usually from a work event, caused by one or two glasses of cheap bubbles.
