In order to understand the forked blocks first, you need to understand the GHOST protocol which is complex also, but as far I know the forked blocks are those blocks that weren't included in the blockchain. Because of the Proof of Work in blockchains like Ethereum which has a block time adjusted to be near of 10-19 seconds, can create a lots of blocks at the same time by different miners and to reduce the centralization and keep rewarding miners the GHOST protocol added the concept of uncle blocks which are blocks that "lost" the race of PoW but because they "almost" won they can be rewarded too with a fraction of the reward, according to rules of the protocol. And forked blocks are those blocks that are mined like uncle blocks, but can't be included in the chain because according to the rules of the GHOST protocol they failed in the race and some requisites, so those blocks are discarded and never added to the blockchain.
