A Certified Draken is someone who goes to lengths much farther than a Karen would, this term was made cause of the rapper/singer "Drake" it is a word that is aimed towards his ego and the pettiness that comes with it like following someone's daughter who just turned 18 (who is also artist named Laila!) over her dad (who happens to be the rapper/singer Mos Def) pretty much calling his music something you would hear in Target in his own words: "It feels like a lot of his music is compatible with... shopping." also Drake seems to have a thing for following peoples ex wives when his poor ego is hurt (in this case Record Producer and DJ Mustard) over producing the song "Not Like Us" by "Kendrick Lamar" and wearing a Toronto Blue Jays hat when it was just the last hat he had during that time. Overall Drake's hurt ego and pettiness makes him go lengths beyond what a Karen would usually do. (You could also use this term against drake fans who try to defend drake or say he somehow won the beef when he clearly lost)
