Latto's smiling somewhere ... after the Toronto Raptors PA man announced rookie Gradey Dick in the most hilarious way during player introductions -- "Mr. Big Dick Energy!"
The WTF moment happened right before the Raptors took on Damian Lillard and the Bucks at Scotiabank Arena in Toronto on Wednesday.
Herbie Kuhn, the Raptors PA announcer since '95, began introducing the Raptors starting lineup ... which for the first time ever, included Dick.
Kuhn made sure GD's first time starting would be very special .
