Villanova star Donte DiVincenzo had a busy night -- after he led the Wildcats to an NCAA title, he deleted thousands of old tweets ... including one that featured the N-word.
As DiVincenzo heated up during the game, people started combing through the 21-year-old's social media history ... and found a tweet from 2011 that read, "Ballin on these N**gas like I'm Derrick Rose."
The line is actually a lyric from a Meek Mill track that came out a week before the tweet -- but the Internet freaked out anyway.
