WT Actual F? Subtle Gray Hidden Profanity Mug

This hidden profanity mug passes every vibe check in the office kitchen. A tidy monochrome zigzag, in a fair isle pattern nobody will clock until they're standing right next to you.
Clean and understated, it's the kind of mug that says "I have my life together." 
But it does NOT have its life together. It says WHAT THE ACTUAL FUCK, over and over.
