Terminally online, thinking and talking entirely in memes. Mr. Brain-Rot’s attention span left the building ages ago.

Great for the chronically online mate, the meme-lord of the group, or anyone whose humour only makes sense to Gen Z.

This mug is a bright white 11oz ceramic mug, printed with a durable full-colour design using AAA+ ORCA coating for long-lasting colour that won’t fade in the wash. It’s dishwasher-safe and microwave-safe, made to order and printed fresh for every customer.

Part of RudeCuppa’s Mouthy Little Mugs collection — small characters with massive attitude.

It’s giving no thoughts, just vibes.
