WBU started in the early internet chat rooms and texting culture when individuals started to abbreviate phrases in order to type more quickly. It gained particular momentum in the 2000s following the emergence of SMS, instant messaging and social sites, such as MSN, Yahoo Chat and subsequently Snapchat and WhatsApp. When communication shifted to the internet, WBU was a convenient method of responding to what about you as fast as possible. It was easy to use and therefore managed to stay a staple of the modern online communication even as newer slangs were developed. VIsit Now: what does wbu mean (https://radarro.com/wbu-meaning/)
