Does bullish mean sell?

Excuse me, but I'm a bit confused by the terminology here. Could you clarify something for me? When someone refers to a market or an asset as 'bullish,' does that actually mean they are suggesting it's time to sell? I've heard the term 'bullish' used in a positive context, implying growth or appreciation in value, so I'm wondering if I've misunderstood the meaning. Could you please explain how 'bullish' is typically interpreted in the world of cryptocurrency and finance?
