About

Jamaican Smile, also known as Jamaican Smiling, refers to an ironic Sigma slang term that riffs on the term similar to other nationality-based terms like German Stare and Balkan Rage. Therefore, the Jamaican Smile is not a real phenomenon and instead, its usage mocks other Sigma brainrot terms like Winter Arc and Balkan Rage and Those Who Know, which were all popularized in late 2024, predominantly used withing Sigma Phonk edits featuring the creepy Trollface variant Trollge.

The Child Coin

Whoever launches this meme first creates its one official child coin of $MEME. The child coin takes this exact image, is priced in $MEME, and pays 1% of its every trade to its holders, in $MEME. After that, the meme is closed here forever.
