Top definition. Vlad. Vlad is usually a Russian name, sometimes romanian, and usually is an athletic all around great guy that is good at everything. He is known to have a big penis and is a legend in bed. He has an amazing body and really funny. He is very popular especially with females...fine females.
Thousands of the citizens of the town that had sheltered his rival were impaled by Vlad. The captured Danesti prince was forced to read his own funeral oration while kneeling before an open grave before his execution. Vlad's atrocities against the people of Wallachia were usually attempts to enforce his own moral code upon his country.
