June 22, 2026

If you've spent any time around Geek Bar, you've seen the name: Fcuking FAB. It's the single most-searched Geek Bar flavor in the USA — but the ridiculous name leaves a lot of people wondering what it actually tastes like. Here's the explainer.

What does Fcuking FAB taste like?

Fcuking FAB is a bold, complex tropical-candy blend. Most vapers describe it as a mix of passion fruit, guava and sweet tropical fruit with a candy-like sweetness and a light, cooling finish. It's punchy and a little hard to pin down — fruit-punch-meets-candy is the closest shorthand. That bold, layered profile is exactly why people love it.

Why is it such a phenomenon?

Two things: the flavor genuinely delivers — it's intense, sweet and satisfying without being one-note — and the attention-grabbing name made it go viral. Together they've made it Geek Bar's most-searched and most-recognized flavor.

Which devices have it?

You'll find Fcuking FAB on the Geek Bar Pulse 15K Patriot Edition, with Sour and Orange twists on the Pulse X 25K, and even a 0mg nicotine-free version. Vape it in Pulse Mode to get the fullest, boldest flavor.
