When your boyfriend comes back to voltron after being on a space whale for two years, in the quantum abyss, with his galra mom and raising a cosmic time wolf then you can use the term Hey Everybody Keith's Back.
One of the many bastard children of The Most Interesting Man In The World. Often spotted with a case of Keystone Light tucked under his arm. Always smooth.
Keith: My name? Is Keith Stone.
Totally hot chick: Keith Stone? You're so smooth...
Keith: Always.
