Means to be Dumb and Smart at the same time, I know sounds confusing but when you'll find that special person and he/she call you Dumbart is because that person was trying to be mean but cute at the same time. And at that moment youll know he/she is going to love you forever.
"Oh my god, you are Dumbart"
"Aw I love you too"
