look up any word, like ethered:
YABHTU is an acronym used mostly by tech bloggers to refer to the highly enjoyable state of owning a tablet PC. It stands for "Yet Another Blissfully Happy Tablet User".
"You know, my roommate has an HP tablet PC. It's incredibly small, and has to have an external disk drive."

"Wow, that sounds... Unfortunate."

"Yep, but she's totally YABHTU."
