WUF
WUF has 2 meanings
Wow, you're funny
In messages, people may send "wuf" as a more creative way to respond to a humorous comment than the typical LOL. Most people use it genuinely to remark on a person's sense of humor (SOH), but they may also use it sarcastically.
For example, you may flirt with a girl you met online through DMs and send her, "wuf. I love that meme! ;)" Or, if you are in a text thread and an annoying acquaintance shares an offensive joke, you may reply with a cold "wuf. did u think of that 1 all by urself?"
Example
I laughed so hard when I gave you bunny ears in that picture!

How well do you know your texting slang?
WUF is typically used in texting or online chats as a casual way to ask someone about their origins or background. It might be one of the first questions someone asks when meeting another person online.
You may see WUF on platforms like Instagram, Snapchat, or TikTok, where strangers often interact with each other. When typing "WUF," you can add a question mark (WUF?), but it is not necessary since the question is implied. People more often use the WYF version.
