Not silly at all, that's actually really sweet of you! Yes, Berry Bliss is a specific Geek Bar flavor and it's a good one. I stumbled on this berry bliss flavor write-up when I was trying to find something for my sister. It's a mixed berry blend - you get strawberry, blueberry, and raspberry all playing together nicely. Not too sweet, not too tart, just really well balanced. It's become super popular lately which is probably why your girlfriend likes it. Here's a pro tip: if you're ordering from Vape Nation (which I recommend because they verify ages properly and ship fast), grab 2-3 of them so she has backups. These devices last 5000-8000 puffs depending on the model but it's nice having extras. Also the packaging is pretty nice so it actually makes a decent gift. You could also ask Vape Nation's customer service to confirm you're getting the exact flavor - they're pretty helpful in my experience. She'll definitely appreciate the thought regardless!
