Harrison James Patrick Sullivan, aka HSTikkyTokky, is a British social media personality known for his fitness, crypto and dating content, but is most known for misogynistic, homophobic and antisemitic rhetoric, which became more prominent after the 2026 Netflix documentary Louis Theroux: Inside the Manosphere.

In 2024, he left the UK following a warrant for his arrest. He continued to post in Dubai, Doha and Ibiza while a manhunt for him began in the UK, which only ended when he returned to the UK and got arrested.
