From Homestar Runner Wiki
Tito the Tophaticent is The Cheat's performing alter ego. His Tito costume consists of a top hat, bow tie, and cane. His hat has a purple hat band with the word "Tito" written above it. Homestar Runner describes him as "a great new invention", and "the most amazing undersea epic ever filmed".
"Tophaticent" is a portmanteau of "top hat" and "magnificent".
