What does HBTU stand for?

Happy birthday to you

Your friends, family, and co-workers may use HBTU to mean "happy birthday to you." As you might expect, you're most likely to receive this acronym on your birthday, in text or chat messages.

Less commonly, people may send HBTU when it's not your birthday, but you have received a "gift" of some kind. For example, if you tell a friend that a test you forgot to study for got postponed, they may respond with "HBTU," as a celebration of your good fortune.


HBTU! And many more!
Thanks, can't believe it's the big 5-0 already
