The 'Ol' Spicy Keychain' is a colloquial and humorous term used to describe pepper spray carried on a keyring for self-defense. The meme gained popularity across platforms like TikTok and Twitter, often featuring individuals humorously brandishing their 'spicy' accessory as a deterrent for unwanted social interactions or awkward situations. It taps into the 'staying safe but making it funny' aesthetic, contrasting a serious safety tool with a whimsical nickname. The template is widely used to joke about being over-prepared, setting boundaries, or dealing with people who simply cannot take a hint.
