The 'Improvise. Adapt. Overcome.' meme features the famous survivalist Bear Grylls from his television series 'Man vs. Wild.' Although the phrase is traditionally a slogan associated with the United States Marine Corps, it became an internet sensation in late 2017 when paired with Grylls' image. The meme is primarily used to illustrate a person's ability to deal with unexpected obstacles, often involving absurd, creative, or unnecessarily dramatic solutions. It captures the spirit of resilience in the face of trivial problems, making it a versatile tool for social commentary on everything from tech issues to everyday life hacks.
