There's quite a few different kind of flops.
1. Universal flop. This is something that failed on every level, critics hate it, fans hate it and its sales were insufficient to make a profit.
2. Critical flop. A game that failed to impress the critics and most likely a majority of the fans. It could still be a commercial success if it had a lot of hype, good marketing or a solid fan-base.
3. Commercial flop. Most critics and consumers could agree that it's a good/great game yet it still couldn't sell well enough to make a profit.
4. Relative flop. A game that despite a good critical reception and selling enough to be profitable, falls significantly below what past games in the series have achieved on average.
