"On Donda" is a phrase that means to tell the absolute truth/swear with conviction; an Oath.
Origin: Donda is Kanye West's mother who passed away. In one of his tweets he used the phrase "on Donda", swearing on his dead mother, that Travis Scott will not allow Drake to diss him on any of future songs they create.
Dashingly delicious chocolate delicacy. People named Donneal are usually doctors, actors, billionaires, pornstars, humanitarians, kings, overall successful people. Very humble and funny once you get to know one.
