There is a trend within rappers to add ‘eezy’ to their last name. For example- Weezy (Lil Wayne), Drizzy (Aubrey Drake Graham), Jeezy (Jay Wayne Jenkins), Eazy-E  (Eric Lynn Wright), and Breezy (Christopher Maurice Brown).

Kayne West did the same thing for his fashion collaboration. His short name is ‘ye’ and he added ‘eezy’ with ye. That’s why people call him ‘Yeezy’.

Kayne West has an album called ‘Yeezus’ which is derived from the name of Jesus. He thought this name will make him the God of the rappers. People often think that for this name ‘Yeezus’ Kyne is called yeezy. But That’s not the reason. For the trend among rappers, they call him ‘Yeezy’.
