Luka Doncic is apparently having a difficult time keeping his postgame interviews PG ... letting yet another F-bomb fly on Wednesday night -- although, as he's done previously, he apologized right away.
The latest potty-mouth incident from the Mavericks superstar happened just after the Dallas point guard netted 40 points, 10 rebounds and 11 assists in a 147-97 win over the Utah Jazz.
Doncic was asked about the importance of the W after his squad had started December with an 0-2 record -- and that's when began cussin'.
"I said before the game, you know, we just can't f*** around," Doncic said.
