The word "opportunistic" is used to describe someone who takes advantage of any chance or opportunity that comes their way, especially if it benefits them. It can refer to someone who exploits a situation for their own personal gain, without considering whether it is fair or ethical. For example, an opportunistic person might take advantage of a co-worker's mistake to get themselves ahead in the company, or they might try to befriend someone just to use their connections or resources. It can also be used to describe an illness that takes advantage of a weakened immune system to attack the body. Basically, when someone or something is opportunistic, they are acting in a calculated way to benefit themselves, without much regard for anyone else.
