The term 'Glizzy' originated in the Washington D.C. area as slang for a Glock handgun, but it eventually transitioned into a viral internet term for a hot dog due to its similar length. The meme gained massive popularity on platforms like TikTok and Twitter during the 'Summer of the Glizzy' in 2020, often featuring people eating hot dogs in impressive or awkward ways. Users frequently refer to those who excel at eating them as 'Glizzy Gladiators.' Today, the meme is used to poke fun at the act of eating hot dogs or simply to replace the word 'hot dog' with its more chaotic, internet-approved slang alternative.
