K3U

K3U is a visual representation of "I <3 U" where the "K" represents the "I" and the bottom half of the heart (I<). People may use it in messages and online to tell others they love them.

For example, you may text your boyfriend, "I had such a great time with you at the park today. K3U!" Or, you might post a picture collage on Instagram for your 1st anniversary, "I can't believe it's been a year already. You have made my life so much better. K3U!!!"

While most people use K3U romantically, they may also use it platonically with a family member, bestie, etc. For example, you might text your mom, "Thanks for picking me up from the airport. K3U, mom!"
