U2

U2 is an acronym people sometimes use in messages to quickly reflect something received, like a compliment or well wishes. For example, if your friend sends you a compliment in a text about how good you look, you might reply by sending "U2!"

People often send U2 in texts or online messages, but you may also see it in other places like social sites and forums. For example, a friend may comment on your Facebook post about losing power due to a storm, saying, "U2? W finally got our power back on this morning. Did you?" Remember that some older folks may be confused by U2 since it is also the name of the world-renowned rock band from Ireland featuring Bono and Edge.
